Influence of (de)protonation on the photophysical properties of phenol-substituted diazine chromophores: experimental and theoretical studies

Abstract

In this contribution, a series of seven push–pull systems has been designed by combining a protonable diazine heterocycle with a deprotonable phenol unit through various π-conjugated linkers (phenylene, thienylene, thienylenevinylene, and phenylenevinylene).
