Alternating quinoxaline/oligothiophene copolymers—synthesis and unexpected absorption properties?

Journal of Materials Chemistry Pub Date: 2007-03-05 DOI: 10.1039/B700271H

Abstract

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.
