Two new C_(60)-glycine ester derivatives C_(60)(EtOOCCHNHCHCOOEt)(A) and C_(60)(PbCH_2OOCCHNHCHCOOCH_2Ph)(B) were synthesized and purified. Their room temperature photoluminescence was measured for the first time from their CHCl3 solutions.It was first observed for fullerenes that their fluorescence could be quenched by concentration. The fluorescence lifetime was determined to be 1.5±0.3 ns for sA and 1.6±0.3 ns for B, respectively, using the frequency-domain method.
