Metal-Like Lustrous Coatings Prepared Without Using Metals

Abstract

Quite recently, we have prepared anion-doped thiophene-based oligomers and found that their cast films exhibited gold-like luster. This review describes the method for the preparation of the oligomers, and the physicochemical properties of the coating films such as external appearance, spectroscopic characteristics (reflection, transmission, and absorption spectral characteristics), film structure, and aging stability in the air.
