Covalent binding of fullerene C-60 to dithienylethene as a promising approach to the preparation of new photochromic compounds

摘要

A dithienylethene-containing fullerocyclopropane was synthesized by the catalytic reaction of the carbon cluster with diazoalkane generated in situ by the oxidation of a corresponding photochrome hydrazone with MnO2 in the presence of the Pd(acac)(2)-2PPh(3)-4Et(3)Al catalyst, and the photochromic properties of the synthesized methanofullerene were evaluated.
