摘　　要：A novel organic chromophore 4, 4＇-bis（9-carbazyl-trans-styryl）-biphenyl （BCSBP） has been synthesized and characterized by IHNMR and elemental analysis. Three-photon absorption（3PA） induced upconvention fluorescence was observed and large 3PA cross section as high as 10^-74 cm^6 s^2 was obtained for nanosecond laser pulses at 1064 nm from optical limiting measurements.A novel organic chromophore 4, 4＇-bis（9-carbazyl-trans-styryl）-biphenyl （BCSBP） has been synthesized and characterized by IHNMR and elemental analysis.
