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. 相似文献

The palladium complexes of highly extended π-electronic conjugation system, octaethylporphyrin(Pd)-(dihexylbithiophene)n-octaethylporphyrin(Pd) [OEP(Pd)-(DHBTh)n-OEP(Pd), n=1-6], were synthesized, in which all the chromophores are connected with diacetylene linkage. The unsymmetrical derivatives of OEP(Ni)-DHBTh-OEP(Pd) were also successfully synthesized. Electronic properties of these symmetrical and unsymmetrical complexes were conclusively described, as compared with those of OEP(Ni)-(DHBTh)n-OEP(Ni). Based on the structure elements, a methodical guiding principle for molecular design of the particular electronic structure will be proposed. 相似文献
