Abstract
A new 4-methoxyphenyl substituted C-60-pyrrolidine derivative, C-60(C1 0H13NO) (1), was prepared and its room-temperature fluorescence was st udied. Its fluorescence intensity is three times stronger than that of C-60. Its singlet energy was estimated to be 25 kJ/mol lower than tha t of C-60. The fluorescence lifetime was determined to be 2.1+/-0.3 ns by using the frequency domain method. The fluorescence quenching by c oncentration and aromatic electron donor: N, N-dimethylaniline (DMA) w as investigated. Data show that its fluorescence could not be quenched by DMA.
