  Synthesis and properties of unsymmetrically extended π-electronic conjugation system of octaethylporphyrin(Ni)–dihexybithiophene–octaethylporphyrin(Pd) connected with diacetylene linkage

  摘要：

  Orientational isomers of the diacetylene-group connected dihexybithiophene (DHBTh) derivatives have been synthesized. in which the different octaethylporphyrin (OEP(M): M=Ni or Pd) rings are attached at the ends. Reflecting the unsymmetrical structural feature, the peculiar electronic properties of the extended OEP(Ni)-DHBTh-OEP(Pd) system were observed. (C) 2003 Elsevier Ltd. All rights reserved.

  The palladium complexes of highly extended pi-electronic conjugation system, octaethyl porphyrin (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. (C) 2004 Elsevier Ltd. All rights reserved.
