A RADICAL CATIONIC DIMER FOR OPTOELECTRONICS

摘要

Macrocyclic oligothiophenes-giant cycles with thiophene segments-are fascinating compounds whose π-conjugation and ability to form functional self-assembled monolayers make them the good candidates for optoelectronic devices. While a number of macrocyclic thiophene oligomers have been reported, the preparation of oligothiophene radical cations has been challenging due to the labile nature of radicals. Atsuya Muranaka, Tohru Nishinaga, Shinobu Aoyagi, Masahiko Iyoda, and co-workers have overcome these limitations by creating a radical cation (l~(・+)), generated from extended π-conjugated thiophene (DOI: 10.1021/jacs.9bl3S73).
