Abstract :
The photophysical properties of the first crown ether-bearing [60]fulleropyrrolidine(CFP) have been studied. The absorption and fluorescence spectra are hypsochromically shifted by metal ions complexation via intramolecular electron transfer. The third-order optical nonlinearity of CFP is measured by time-resolved degenerate four-wave mixing experiment. The third-order optical susceptibility χ3 of CFP is 8.97x10−14 esu. The nonlinear optical temporal response is second-order exponential, the fast process is determined as 120 ps.
