A series of electrophosphorescent fluorene-alt-carbazole copolymers are synthesized by Suzuki polycondensation. A 尾-diketone-terminated alkyl chain grafted to the N-position of carbazole serves as a ligand to form a pendant cyclometalated Ir complex with 10-methyl-dibenzo[a,c]phenazine (Mpq), 2,3-diphenylquinoxaline (Bpq), and 1-(benzo[b]thiophen-2-yl)isoquinoline (Biq), resp. The emission of the device of PFCzIrBiq peaked at 715 and 790 nm, which is among the deepest red emissions reported so far. The well-achieved device performances could be attributed to a combination of a higher triplet energy and suitable HOMO/LUMO energy levels which can assure efficient charge injection as a result of the incorporation of a 3,6-carbazole unit into a polyfluorene backbone. In the experiment, the researchers used many compounds, for example, 2-Methyldibenzo[f,h]quinoxaline (cas: 536753-86-3Computed Properties of C17H12N2).
2-Methyldibenzo[f,h]quinoxaline (cas: 536753-86-3) belongs to quinoxaline derivatives. Quinoxaline derivatives are important constituents of pharmacologically active compounds, including antibacterial, antibiotic and antineoplastic, antifungal, anti-inflammatory and analgesic drugs. Quinoxalines are used as dyes, pharmaceuticals, and antibiotics such as echinomycin, levomycin exhibiting antitumoral properties. Quinoxalines establish also the basis of anthelmintics and receptor antagonists.Computed Properties of C17H12N2
