Abstract: Two new C60-glycine ester derivatives C60(EtOOCCHNHCHCOOEt)(A) and C60(PbCH2OOCCHNHCHCOOCH2Ph)(B) were synthesized and purified. Their room temperature photoluminescence was measured for the first time from their CHCl3solutions.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.

Key words: C60-Glycine ester derivative, Concentration quenching, Fluorescence lifetime
