Exploration of naphtho[c]dithiophenes: synthesis and optical and electrochemical properties of naphtho[1,2-c:5,6-c′]dithiophenes

Abstract

An efficient synthetic method for naphtho[1,2-c:5,6-c′]dithiophenes and their tetrasubstituted derivatives has been developed and their photophysical and electrochemical properties were investigated. The naphtho[c]dithiophene skeleton as a new thiophene-fused polycyclic aromatic system can be used as a π-building block in emitters, semiconductors and photosensitizers for organic optoelectronic devices.
