Abstract

Two new push-pull chromophores based on triphenylamine as donor and 2-carboxymethyl-2-cyanomethylenethiazole as acceptor have been synthesized. Both exhibit strong light absorption covering from 300 to 800 nm. Electrochemical studies show HOMO-LUMO gaps of 2.01 and 1.54 eV, making, together with the panchromatic absorption, these systems promising materials in the field of molecular photovoltaic devices.
