METHOXY-SUBSTITUTED NAPHTHOTHIOPHENES – SINGLE MOLECULES' VS. CONDENSED PHASE PROPERTIES AND PROSPECTS FOR ORGANIC ELECTRONICS APPLICATIONS

Abstract

In this work, a series of tricyclic naphthothiophenes – photocyclization products (8- methoxynaphtho[1,2-b]thiophene (1a); 6,7-dimethoxynaphtho[1,2-b]thiophene (1b); 8- methoxynaphtho[2,1-b]thiophene (2a) have been studied. All compounds possessing similar structures demonstrated the close optical, electrochemical characteristics. Spectroelectrochemical investigation showed that 1b and 2a are able to form stable radical particles at 1.55 V. In case of 1a, the formed at 1.55 V radical is short-living.
