Nanoporous gold assemblies of calixarene-phosphine-capped colloids

Abstract

The synthesis of high surface-area colloidal assemblies of calixarene-phosphine-capped nanoporous gold is reported under reductive electrochemical conditions. These materials uniquely exhibit a remarkably thin wall thickness down to 10 nm, while possessing pore sizes on the order of up to hundreds of nanometers, which can be controlled via choice of organic ligand.
