Abstract	Laser flash photolysis technique was employed to characterize the triplet excited state behavior of C-60-dexamethasone (C-60-DE) in benzene. The time-resolved triplet-triplet (T-T) difference absorption spectrum of C-3(60)-DE * with optical excitation (355 nm laser pulse) was recorded. The spectrum of C-3(60)-DE * exhibited maxima at 700, 440, 350, and 310 nm. The bleaching maximum observed at 330 run coincides well with the ground-state maximum in this region. C-3(60)-DE * could be quenched by oxygen. Compared with C-3(60) , the T-T annihilation rate constant of C-3(60)-DE deduced ((5.03 +/- 1.31)x 10(9) L . mol(-1) . s(-1) for C-3(60) * and (3.53 +/- 0.87)x 10(9) L . mol(-1) . s(-1) for C-3(60)-DE ), and the life time of C-3(60)-DE increased ((12.0 +/- 2.6) mu s for C-3(60) , (18.0 +/- 3.3) mu s for C-3(60)-DE ). The reason may be that the connection of dexamethasone decreased the colliding probability of the C-60 ball.
