Exploration of naphtho[c]dithiophenes: synthesis, 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']dithiophene and its tetrasubstituted derivative have been developed and their photophysical and electrochemical properties were revealed. The naphtho[c]dithiophene skeleton as a new thiophene-fused polycyclic aromatic systems would be used as a π-building blocks in the emitters, semiconductors and photosensitizers for organic optoelectronic devices.
