Through this paper we are proposing chemically modified fullerol as a fluorescent indicator. We examined the esterification of a fullerol, C-60( OH)(n), and determined the emission properties which have been directly linked to their chemical structures. As "fullerol'' is a mixture of polyhydroxylated fullerenes, the separation of C-60(OH)(n) and their esters have been attempted by using polyacrylamide gel electrophoresis ( PAGE).
