Abstract

A series of host-guest complexes of tungsten(VI)-oxo calixarenes substituted with two bithiophene groups at the upper rim were prepd. The bithienyl tungsten(VI)-oxo calixarenes were prepd. by Stille coupling of the complex with 2-tributylstannyl bithiophene and hydrolysis of the glycol ligand yielding the monomer precursor as the DMSO adduct. Upon removal of DMSO, the complex readily reacted with substituted formamides to produce the host-guest adduct monomers. These adducts undergo electrochem. polymn. that results in conducting polymers that contain guest mols. inside the calixarene cavity. The cond. of the polymers is dependent on the nature of the guest, being significantly lower for the disubstituted formamide complexes. [on SciFinder(R)]
