Synthesis and structural and electronic properties of the octaethylporphyrin-dihexylbithiophene-fullerene derivatives (OEP-DHBTh-C60) connected with diacetylene linkage

Orientational isomers of the octaethylporphyrin-dihexylbithiophene-fullerene derivative (OEP-DHBTh-C60) connected with the diacetylene linkage were synthesized. The electronic and electrochemical properties were studied, proving that the orientation of DHBTh affects not only the electronic structures of OEP-DHBTh-C60 but also their molecular motional behaviors evidently.
