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 synthesis and characterization is reported of six 2,5-distyryl-heteroarylenes (BXB compounds) and 1,4-bis{ 2-(heteroaryl-2-yl) ethenyl}benzenes (XBX compounds) containing the thienyl, furanyl or N-methylpyrryl as the heteroarylene moiety. By means of NMR and UVNis spectroscopy the electronic str
