Synthetic Approach to and Characterization of a Fullerene–DTBT–Fullerene Triad

Abstract

The synthesis of a new fullerene–dithienylbenzo[c]thiophene (DTBT)–fullerene triad is reported. The synthetic approach involves the synthesis of a DTBT unit, a Sonogashira reaction to introduce two acetylenic groups, and the coupling with fullerene. The product showed an absorption at λ = 485 nm and a fluorescence band at λ = 575 nm.

Key words

alkynes - arylation - fullerenes - heterocycles - palladium
