Dj. Zhou et al., ROOM-TEMPERATURE FLUORESCENCE OF C-60-GLY CINE ESTER DERIVATIVES IN SOLUTION, Gaodeng xuexiao huaxue xuebao, 16(10), 1995, pp. 1512-1513
Two new C-60-glycine ester derivatives C-60 (EtOOCCHNHCHCOOEt) (A) and
C-60 (PhCH(2)OOCCHNHCHCOOCH(2)Ph) (B) were synthesized and purified,
Their room temperature photoluminescence was measured for the first ti
me from their CHCl3, solutions, It was first observed for fullerenes t
hat their fluorescence could be quenched by concentration, The fluores
cence lifetime was determined to be 1.5 +/- 0.3 ns for A and 1.6 +/- 0
.3 ns for B, respectively, using the frequency-domain method.
