Regulating Photophysical Property of Aggregation-Induced Delayed Fluorescence Luminogens via Heavy Atom Effect to Achieve Efficient Organic Light-Emitting Diodes was written by Xu, Jingwen;Wu, Xing;Li, Jinshi;Zhao, Zujin;Tang, Ben Zhong. And the article was included in Advanced Optical Materials in 2022.Application In Synthesis of Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile This article mentions the following:

Heavy atom effect is beneficial to delayed fluorescence by enlarging spin-orbit coupling (SOC). The introduction of halogen atoms to luminogenic mols. is a widely used approach to realize heavy atom effect, but the positions of halogen atoms may exert quite different impacts on the photophys. properties of the mols. To confirm this hypothesis, herein, bromine atoms are introduced on a delayed fluorescence luminogen comprised of benzoyl acceptor and phenoxazine and phenylcarbazole donors at different positions. The resultant luminogens show great differences in photoluminescence (PL) efficiencies and delayed fluorescence lifetimes in solid state, which could be attributed to different orbital contribution ratios of bromine atoms to mol. frontier orbitals and thus varied SOC interactions, as revealed by spectroscopy, crystallog., and theor. calculation The luminogens with bromine atoms on the phenylcarbazole units hold much better PL properties than those with bromine atoms on other positions, and behave efficiently as emitters in organic light-emitting diodes, furnishing high external quantum efficiencies of up to 28.6% and small efficiency roll-offs. The structure-property relationship gained in this work can provide guidance for the further design of efficient luminescent materials. In the experiment, the researchers used many compounds, for example, Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4Application In Synthesis of Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile).

Highly Efficient Deep-Blue Phosphorescent OLEDs Based on a Trimethylsilyl-Substituted Tetradentate Pt(II) Complex was written by Park, Hea Jung;Jang, Jee-Hun;Lee, Jeong-Hwan;Hwang, Do-Hoon. And the article was included in ACS Applied Materials & Interfaces in 2022.HPLC of Formula: 105598-27-4 This article mentions the following:

Compared to Ir(III) complexes with octahedral geometries, Pt(II) complexes with square planar geometries show superior optical properties because their flat shapes lead to an orientation that enhances the outcoupling of organic light-emitting diodes (OLEDs). However, the flat shapes of Pt(II) complexes typically induce a bathochromic shift, limiting their application in high-performance deep-blue phosphorescent OLEDs with high color purity. In this study, bulky trimethylsilyl (TMS)-substituted blue phosphorescent Pt(II) complex (PtON7-TMS) is successfully synthesized to improve color purity. The TMS substituent containing Si atom effectively suppresses intermol. interaction and aggregation even when the complex concentration in the film state is higher than 30 wt %. As a result, the PtON7-TMS-based OLEDs exhibit a maximum external quantum efficiency of 21.4%, along with a pure-blue color of CIE (0.14, 0.09) at 20 wt % doping concentration and a full-width at half maximum of 30 nm. The pure blue color is maintained at a higher doping concentration (>30 wt %). In the experiment, the researchers used many compounds, for example, Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4HPLC of Formula: 105598-27-4).

Four red homoleptic iridium (III) complexes (Ir1-Ir4) with steric phenylphthalazine ligands have been synthesized. Single X-ray structural anal. shows that the steric hindrance groups can prevent mol. aggregation. All complexes exhibited red emission with peaks between 614 and 629 nm in CH₂Cl₂ and photoluminescence quantum yields (QYs) of 44%-86% in doped films. They were concentration-insensitive, their QYs in neat powder and air atm. can reach a maximum of 15%. These complexes exhibited excellent thermal stability with T_d higher than 416 °C. The OLEDs based on these complexes showed good performances at 10 wt% high doping concentration Especially, the device based on Ir1 gave a peak current efficiency and external quantum efficiency (EQE) of 25.0 cd A^-1 and 24.2% with mild efficiency roll-off, which is the most efficient OLED based on phthalazine iridium complexes. The maximum EQEs of non-doped devices are between 4.0% and 5.6%, which are considerably high, compared with the reported efficiency of iridium complexes based red-emitting non-doped devices. These studies show that increasing the d. of the rigid steric groups of iridium complexes is very effective to achieve high efficiency and low concentration sensitive red phosphorescent devices.

The luminescence properties and photophys. mechanism of a spiro-acridine based mol. DBPz-2spAc in toluene and aggregation states is theor. predicted. The solid state can effectively suppress nonradiative energy loss and thus improve luminescence efficiency. Organic LEDs based on DBPz-2spAc show high luminescence efficiency. Studies based on spiro-acridine derivatives indicate that bending the degree of acridine in excited state will directly affect the nonradiative energy loss. The understanding is improved of the luminous behavior of spiro-acridine derivative-based thermally-activated delayed fluorescence (TADF) emitters in solution and in aggregation state, which should pave the way for the design of efficient deep red TADF materials.

And the article was included in Advanced Optical Materials in 2022.Recommanded Product: Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile This article mentions the following:

High-performance deep-blue fluorescent materials matching the required Commission Internationale de l′Eclairage y coordinate value (CIEy) of < 0.08 are much-needed in organic light-emitting diodes (OLEDs) for realizing the perfect application of full-color displays. However, deep-blue fluorophors commonly show unsatisfactory performance due to the intrinsic large bandgap characteristic. Here, the deep-blue nondoped OLED with the good CIE coordinates of (0.15, 0.07) and external quantum efficiency (EQE) of ≈9% is achieved based on a multifunctional and efficient anthracene-based fluorophor (2M-ph-3CzAnBzt). Using it as a host, the sky-blue fluorescent OLED realizes the maximum EQE of 9.50%, and keeps as high as 9.27% and 8.56% at 1000 and 5000 cd m^-2. More surprisingly, high-performance hybrid white OLEDs (WOLEDs) with good color stability and low roll-off are achieved by using it as the blue emitter. Two-color WOLED shows the forward-viewing efficiencies of 20.46%, and 76.80 lm W^-1. The three-color WOLED emitting a candlelight with the color rendering index of ≥ 82 realizes the maximum EQE of 21.49% and remains 20.80% at 1000 cd m^-2. Such superior electroluminescence performance achieved in these OLEDs ranks among the highest values based on deep-blue fluorophors with CIEy < 0.08.

Chiral thermally activated delayed fluorescence (TADF) mols. showing circularly polarized luminescence (CPL) have great potential in 3D displays. However, the relationships among CPL property, device performance and mol. structure are still not clear. In this article, we develop a strategy to promote dissymmetry factors without sacrifice in device performance and study the impact of mol. structures towards CPL property. Three novel TADF enantiomers are synthesized and studied. (R/S)-SCN with diminutive cyano group as an acceptor shows dissymmetry factor |g_PL| ∼ 1.4×10^-3 and noticeable organic light-emitting diode (OLED) performances with a maximum external quantum efficiency (EQE_max) of 23.0%. For (R/S)-SPHCN, the prolonged electron withdrawing group benzonitrile enhances |g_PL| up to 3.6×10^-3 with decreased device EQE_max of 15.4%. By further replacing benzonitrile with (trifluoromethyl)pyridine, the enantiomers of (R/S)-SCFPY show similar |g_PL| factors of 3.5×10^-3 and device EQE_max up to 23.3%, which represents the highest efficiency among sprio-type TADF materials based OLEDs. Furthermore, the OLEDs also show obvious circularly polarized electroluminescence with g_EL factors of -1.4/1.8×10^-3, -3.6/3.6 x10^-3 and -3.7/3.6×10^-3, resp. These results indecate by delicate functional group engineering, high g factor can be achieved while maintaining decent device performances. Besides, (R/S)-SCFPY represents an impressive TADF emitter, which shows promoted g factor and recorded high device EQE_max among similar mols.

We synthesized a diphenylamine modified pyrene derivative, 4,9-diisopropyl-N,N,N’,N’-tetrakis-(4-methyl-biphenyl-3-yl)-pyrene-1,6-diamine (DITBDAP), and successfully applied it to deep-blue organic light-emitting diodes (OLEDs). The DITBDAP-based top-emitting OLED was featured by a high maximum external quantum efficiency (EQE_max) of 20.6%, an extremely low CIE_y (Commission International de L’Eclairage coordinates) of 0.04, a narrow full-width at half maximum of 16 nm, and a long lifetime of 250 h. We chose 6,12-bis[6-trimethylphenylamino-5-trimethylphenylamino] pyrene (Bmpac) as the comparison material due to its similar structure to DITBDAP. The DITBDAP-based bottom-emitting OLED showed a better performance compared to that of the Bmpac-based OLED, with the T₉₅ lifetime (time to 95% of the initial luminance of 3000 cd m^-2) of 250 h, which was more than twice that of the Bmpac-based OLED. In addition, the efficiency roll-off was extremely low at high brightness, which were 1% at 1100 cd m^-2 and 5% at 3200 cd m^-2. The synthesized DITBDAP has realized highly efficient and long-lifetime deep-blue OLEDs with the EQE up to 20.6% and CIE_y as low as 0.04.

In situ coordination-activated n-doping by air-stable metals in electron-transport organic ligands has proven to be a viable method to achieve Ohmic electron injection for organic optoelectronics. However, the mutual exclusion of ligands with high nucleophilic quality and strong electron affinity limits the injection efficiency. Here, we propose meta-linkage diphenanthroline-type ligands, which not only possess high electron affinity and good electron transport ability but also favor the formation of tetrahedrally coordinated double-helical metal complexes to decrease the ionization energy of air-stable metals. An electron injection layer (EIL) compatible with various cathodes and electron transport materials is developed with silver as an n-dopant, and the injection efficiency outperforms conventional EILs such as lithium compounds A deep-blue organic light-emitting diode with an optimized EIL achieves a high current efficiency calibrated by the y color coordinate (0.045) of 237 cd A-1 and a superb LT95 of 104.1 h at 5000 cd m-2.

White organic light-emitting diodes (WOLEDs) with high efficiencies and tunable colors attracts considerable interest from the industry and academia. Thermally activated delayed-fluorescence (TADF) emitters can revolutionize such WOLED devices; however, they still suffer from poor performances. In this study, an advanced double-emissive-layer device architecture capable of hole-trapping TADF-sensitized emissions is proposed to not only achieve a recombination zone shift for the tunable colors but also accelerate exciton emission dynamics for high efficiency and alleviated roll-off. The proof-of-concept WOLEDs exhibit significant shifts in their Commission Internationale de l′Eclairage (CIE) coordinates and correlated color temperatures from (0.40, 0.47) and 4088 K at 100 cd m-2 to (0.27, 0.33) and 9269 K at 5000 cd m^-2. Addnl., the maximum external quantum efficiency (EQE) reaches 30.7% and remains >25% over a wide luminance range of 500-5000 cd m^-2, along with an extended LT80 of over 20 000 h at an initial luminance of 100 cd m^-2.
