A Stable Room-Temperature Molecular Assembly of Zwitterionic Organic Dipoles Guided by a Si(111)-7x7 Template Effect

Abstract

Chiral Assemblies of Achiral Molecules: High resolution STM images of zwitterionic organic dipoles deposited on Si- (111)-7x7 show a chiral molecular assembly on this surface . Density functional calculations demonstrate that a sulfonato group can act as an electrostatic shield that protects the pi-skeleton of organic molecules from the dangling bonds of semiconductor surfaces, which is a major advance in the deposition of pi-conjugated molecules.
