- Аннотация: Triphenylamine (TPA) derivatives are well known photoconducting materials with high hole mobility. TPA-derivatives have been widely investigated as promising materials for organic electronics [1]. Recently a number of star-shaped molecules based on TPA and containing oligothiophene as π-bridges and alkyldycianovinyl groups as acceptor units have been synthesized [2,3,4]. These star-shaped molecules have been widely investigated as one of the most promising materials for organic photovoltaics. However, there is a need to optimize photophysical properties of TPA-based oligomers. In this work, TPA core was modified using carbazole, which is more planar analog of TPA. Also, this work shows the synthesis of a series of oligomers having novel electron donating tris(2-methoxyphenyl)amine core and novel acceptor units –3-ethylrhodanine groups [5]. Besides,we demonstrate series of push-pull unsymmetrical oligomers based on electron-donating TPA and electron-withdrawing dicyanovinyl group. Fig. 1. Schematic representation of star-shaped carbazole-based oligomers (a) and oligomers based on triphenylamine. Variations of parameters of their chemical structures such as type of acceptor and donor groups were used to study the structure-properties relationships in this new type of molecules. This work was supported by Russian Foundation for Basic Research (grant 16-33-01123). The work in the part of synthesis and investigations of star-shaped oligomers was supported by Russian Science Foundation (14-13-01380). 1. Y.N. Luponosov, A.N. Solodukhin, S.A.
