The novel porphyrin 5,15-di（pheny）-10,20-di-[（4-N-imidazolyl） phenyl]porphyrin（H_2Pp） was synthesized by the Alder method and confirmed by elemental analyses,FT-IR,-1HNMR,MS and UV-Vis,etc. The effects of the dosage of catalyst,the appropriate ratio of reactants,reaction temperature and time on the yield of the target compound were investigated. The results show that the yield of the target compound reaches 36. 6% when the suitable reaction time is 1 h and the temperature is 140 ℃.It shows intense fluorescence emission with maximum at 666 nm upon 400 nm excitation at room temperature,indicating that it may be candidate for luminescent material.
