Paulus, Fabian published the artcileN,N’-Dihydrotetraazapentacenes (DHTA) in thin film transistors, HPLC of Formula: 25983-14-6, the main research area is dihydrotetraazapentacene thin film transistor hole mobility field effect.
The synthesis and structural properties of three N,N’-dihydrotetraazapentacenes (DHTA) are described. The different substitution pattern (H, F, Cl) of the dihydrotetraazapentacene body exhibited a significant effect on the optical, electronic and morphol. properties of the derivatives in thin films. The synthesized materials were investigated as active layers in top gate/bottom contact (BC/TG) transistors. The transistor performance of the dichlorinated derivative was almost independent on the processing conditions with an average hole mobility of ∼0.04 cm2 V-1 s-1 and best mobility values ranging from 0.07 to 0.11 cm2 V-1 s-1. Each of the three derivatives was found to exhibit an individual packing motif in solution grown crystals, determined by single crystal x-ray anal. Surprisingly, for all three materials a different polymorph formed in spin cast films explaining the observed morphol. and FET performance.
