摘要：
The optical and electronic properties of novel, alternating quinoxaline/oligothiophene donor-acceptor copolymers show an unexpected independence of absorption and photoluminescence, as well as of the HOMO/LUMO energy levels, on the length of the oligothiophene segments in the copolymer main chain.
