✦ Synopsis

On the basis of the preparation of two 2-pyrazoline compounds, 1,5-diphenyl-3-nitrophenyl-2-pyrazoline and 1,5-diphenyl-3-styryl-2-t~yrazoline, the steady-state photophysical properties have been studied. Results indicated that there is a close relationship between a good l:uorescence probe and the intramolecular charge transfer extent, and the strong intramolecular charge transfer is essential for a good I tuorescence probe.
