Abstract

2,5,8,11,14,17-Hexamethyltriphenyleno[2,1-b:3,4-b’:6,5-b’’:7,8-b’’’:10,9-b’’’’:11,12-b’’’’’]hexathiophene has been synthesized by an iron(III)mediated oxidative cyclization of hexakis(2-methyl-4-thienyl)benzene, and its structure has been determined by an X-ray crystallographic analysis. Electronic properties were investigated by spectroscopic and electrochemical measurements.
