A Molecular Design towards a Highly Amphoteric and Polar Molecule (HAPM) to Assemble Novel Organic Solid-State Structures (INTERFACE SCIENCE-Molecular Aggregates)

Abstract

A molecular design towards a highly amphoteric and polar molecules (HAPM) to fabricate a novel molecular assembly with notable electronic properties is proposed. This design stresses the combination of electrondonating and accepting segments with a pseudo-delocalized π-electron system. To examine the suggested contrivance, 2-(4-dicyanomethylenecyclohexa-2, 5-dienylidene)-4, 5-ethylenedithio-1, 3-dithiole, 1, was designed and synthesized as a test molecule. Results from semiempirical MO calculations and several kinds of experiments imply most characteristics expected for HAPM in principle.
