A novel series of copolymers containing 2,5-dicyano-1,4-phenylene-vinylene--synthetic tuning of the HOMO and LUMO energy levels of conjugated polymers
A series of copolymers of 2,5-dicyano-1,4-phenylenevinylene and 2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene were synthesized by Wittig reaction. The HOMO and LUMO energy levels of copolymers can be easily tuned by controlling the feed ratio of co-monomers.
