designed anthracene bisimide (ABI) derivatives having two triphenylamine (TPA) groups as donor units at the 9,10-positions to form a novel π-conjugated donor–acceptor system. These compounds and their analogues with ethynylene linkers were synthesized by Suzuki–Miyaura and Sonogashira coupling reactions, respectively. In UV–vis spectra, the linker-free derivatives showed broad absorption bands arising

Donor–acceptor–donor arrays based on an anthracene bisimide (ABI) skeleton appended with 6,13-diethynylpentacene and 9,10-diethynylanthracene units have been constructed by Sonogashira coupling followed by reductive aromatization. Their photophysical and electrochemical properties are compared with those of the corresponding mono-substituted analogs on the basis of theoretical calculations and cyclic voltammetry to evaluate the intramolecular electronic interactions between ABI as the acceptor unit and diethynylacene as the donor unit.
通过 Sonogashira 偶联和还原芳香化,我们构建了基于蒽二亚胺(ABI)骨架的供体-受体-供体阵列,并在其中添加了 6,13-二乙炔基五苯和 9,10-二乙炔基蒽单元。在理论计算和循环伏安法的基础上,将它们的光物理和电化学性质与相应的单取代类似物进行了比较,以评估作为受体单元的 ABI 与作为供体单元的二乙炔基乙炔之间的分子内电子相互作用。

A new n -type semiconductor family for organic field-effect transistors (FETs), based on core-unsubstituted and core-cyanated anthracenedicarboximides, is reported. By tuning electron affinity, these materials exhibit good electron-transport properties and stability in ambient as well as very high I (on)/I (off) ratios. Unoptimized N,N '-di-fD ctyl-9,10-dicyano-2,3:6,7- anthracenedicarboximide (ADI8-CN2)-based FETs exhibit good electron mobilities (f(e) = 0.02 cm(2)/(V s)) and very high I (on)/I (off) > 10(7) in ambient conditions.
