Abstract

A porphyrin complex, zinc(II) tetrakis(phenylbutadiynyl)porphyrin, is constructed through meso-substitution approach, which exhibits remarkable bathochromism in absorption and fluorescent spectrum. Both the Q bands in the absorption spectrum and the emission band are red-shifted to the saturated red region. The theoretical analysis showed that the meso-phenylbutadiynyl groups significantly extended the π-conjugation from the porphyrin core to the meso aryl groups.
