Effect of Terminal Donor Units on the Electronic and Photovoltaic Properties of Conjugated Small Molecules: A DFT/TD-DFT Study
Isoindigo-based donor–acceptor small molecules are promising candidates for organic photovoltaic applications because of their strong electron-accepting character and tunable π-conjugated structures. In this work, seven isoindigo-based derivatives bearing phenyl, thiophene, thiophene, benzothiophene, fluorene, carbazol...
