英文摘要：

Two triphenylamine muhibranch chromophores N, N, N-tris-[4-（2-{ 4-[5-（ 4-tert-butyl-phenyl）-1, 3,4- oxadiazol-2-yl]-phenyl}-vinyl）-phenyl]amine（1） and N, N, N-tris[4-{ 2-（3,5-di- { 5-[4-（tert-butyl） phenyl]-1,3, 4-oxadiazol-2-yl） phenyl）-1-ethenyl） phenyl] amine（2） were prepared using Heck reaction. The absorption, single photon excited fluorescence, two-photon excited fluorescence spectra have been recorded. Using 400nm excitation wavelength in CHCl2, the single-photon excited fluorescence of 1 is in the green region with a peak at 536nm and chromophore 2 in the blue region with a peak at 487 nm. The very strong frequency-upconverted fluorescence emission with the central wavelength at 541nm and 518nm in the solution of CHCl2 can be easily observed from chromophores 1-2 solution excited with a Nd. YAG pumped dye laser at the wavelength 800nm in CHCl2 at a concentration of 10^-2mol/L.
