high-resolution FAB MS spectrometry. Optical and electrochemical properties of the products were determined by UV–vis spectroscopy and cyclic voltammetry using Ag/AgNO3 as a reference electrode (solvent: dichloromethane; counter electrode: Pt; electrolyte: n-Bu4NClO4). An insoluble thin film was produced on the glassy carbon and ITO electrode surfaces by the electrochemical oxidation of dithienylthienotr
