Facile synthesis of multifullerene-OPE hybrids via in situ ethynylation

A series of fullerene-terminated oligo(phenylene ethynylene)s (OPEs) (1a-d and 2) have been synthesized and further characterized by cyclic voltammetry (CV) and UV-vis spectroscopy. The key step in the syntheses is an effective one-pot reaction that allows the attachment of C-50 to multiple terminal alkynes.
