中文摘要	Two novel star-shaped donor-acceptor small molecules TPA-TBT-CN and TPA-TBT-R, with triphenylamine (TPA) as the core, benzothiadiazole (BT) as the arm, and alkyl cyanoacetate or 3-ethylrhodanine used as the end-group are synthesized for the application as donor materials in OSCs. The two small molecules films show broad absorption band from 300 nm to 850 nm, narrow optical band gaps (1.5-1.7 eV), deep HOMO energy levels (– 5.0 to – 5.1 eV) and moderate hole mobilities. OSCs based on blends of the two donors and PC70BM acceptors exhibit power conversion efficiencies of 1.34% and 1.79%, respectively. Notably, TPA-TBT-R with 3-ethylrhodanine as the end-group displays broader solar spectral coverage, lower HOMO level, higher hole mobility and higher photovoltaic properties. Our results indicate that 3-ethylrhodanine as the acceptor and end-group is a promising linker in constructing donor materials for high efficiency OSCs.
