Synthesis and properties of porphyrin derivatives conjugated with pyridine ring

Abstract

Orientational isomers of the octaethylporphyrin-dihexylbithiophene-pyridine system (OEP-DHBTh-Py) were synthesized, by the oxidative cross-coupling reactions of the corresponding terminal acetylenes. Based on the experimental results of the protonation to the Py ring, the orientational effect of DHBTh on their electronic structures were studied. The curious features of this system in structure-property relationship will be reported in detail.
