摘要

Abstract A convenient synthesis of a number of oligomeric thiophcnes and oligomeric methyl- , and ethyl-substituted thiophenes as building blocks for novel conducting polymers is reported. The synthesis is based on a NiCl2 (dppp)(dppp= Ph2PCH2CH2CH2; PPh2) catalyzed coupling reaction between appropriately substituted bromothiophenes and Grignard compounds derived of them. The λmax of the UV spectra of the unsubstituted ...
