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 lambda = 485 nm and a fluorescence band at lambda = 575 nm.
