摘要

A series of 4, 4′-π-conjugated-2, 2′-bipyridine chromophores (MS 1–8) were synthesized, and their photophysical and thermal properties were investigated. The title “push– pull'chromophores”, except MS 1, were integrated with both alkoxy and alkylamino donor functionalities that differ in their donation capabilities. The oligophenylenevinylene (OPV) chromophores MS 4–8 are associated with a π-extended backbone in which the position ...
