Abstract:
The reversible acid-base isomerization of fullerene C60 hybrid compounds with spiropyrans has been performed for the first time. It has been found that irradiation induces isomerization only for hybrid bearing NO2 group in the photochromic spiropyran part, while the treatment with trifluoroacetic acid induces isomerization for compounds containing NO2, Cl or F, i.e. irrespective of the nature of substituent in the spiropyran moiety.
