Thiol Functionalized Diphenyl Bithiophene for Monomolecular Bistable Layers

Abstract

Diphenyl bithiophene derivatives (DPBTs), known for their electrical bistable behavior, have been used in bulk resistive memory cells. In this article, we present the design and synthesis of a ω-alkyl thiol functionalized 3,3′-diphenyl 2,2′-bithiophene; such functionalization confers the ability to anchor on a metal surface, which may be conveniently applied for the development of monomolecular bistable devices.
