Functional Molecules for Grafting onto Ionic Surfaces

Abstract

AbstractThe 2D adsorption of molecules onto insulating surfaces is of increasing interest for future devices in emerging technologies such as molecular electronics, sensors, single‐molecule optics, and on‐surface synthesis. However, most attempts to stabilize molecular structures on these substrates have been hampered by weak molecule–surface interactions and so there is a need to develop organic molecules bearing suitable grafting groups. We report herein the synthesis of a series of molecules designed to be physisorbed onto alkali halide crystalline surfaces. They comprise a rigid central benzene or triphenylene core bearing, respectively, two or six alkyl ether chains terminated by cyano, carboxylic, α‐amino acids, or 1,2,3‐triazoles as anchoring groups.
