Given the advances within zeolite chemistry since these initial attempts, and in the light of the intense current interest in so-called “insulated molecular wires”, 5a reconsideration of the ability of S 2 N 2 to polymerise within porous systems becomes germane, especially given that conducting materials such as polyacetylene have been successfully incorporated into zeolite hosts. 5b Introducing the intrinsically conducting (SN) x wire into such a host is a conceptually obvious ...
