Different methods for the coupling of 2-(4-pyridyl)thiophene to alpha-
dibrominated thiophene oligomers and their efficiency to produce a hom
ologous series of extended di(4-pyridyl)thiophene oligomers have been
studied. The coupling was found to be most efficient with the organozi
nc derivative of 2-(4-pyridyl)thiophene, using a Pd(dppf) complex as t
he catalyst in the coupling reaction. The resulting compounds are prom
ising new models for trans-membrane molecular conductors.
