Communication: The production of molecularly isolated polymers as molecular wires is a method of controlling the factors? such as microstructure, morphology, counter-ion, etc., which influence the properties of the material. Here, porous Vycor glass is used as the host material, Cu-2 circle plus ions which have been previously introduced into the 20-200 Angstrom pores promoting the polymerization of pyrrole by reduction. The synthesis and properties of the new material are presented.79792&
