【摘要】 用固相法合成了2个噁二唑衍生物类有机化合物:5-(4-叔丁基苯基)-[1,3,4]噁二唑-2-苯乙烯基-4-苯基-二苯胺(化合物1)与9-乙基-3,6-双{5-(4-叔丁基苯基)-[1,3,4]噁二唑-2-苯乙烯基}-咔唑(化合物2),并测定了它们的吸收光谱、单光子荧光光谱和双光子荧光光谱。化合物1和2在二氯甲烷溶液中单光子荧光发射峰分别位于519和476nm。在锁模Nd∶YAG激光器800nm激光照射下,化合物1和2发射出很强的双光子上转换荧光,其最大波长分别在520和485nm。更多还原

【Abstract】 Two 1,3,4-oxadiazole derivatives {5-(4-tert-Butyl-phenyl)-oxadiazol-2-yl-phenyl-vinyl}-4-phenyl-diphenyl-amine(1) and 9-Ethyl-3,6-bis(2-{4-[5-(4-tert-butyl-phenyl)-oxadiazol-2-yl]-phenyl}-vinyl)-carbazole(2)were prepared using solid state synthesis.The absorption,single photon excited fluorescence,two-photon excited fluorescence spectra have been recorded.Using 400nm excitation wavelength in CHCl2 at a concentration of 10-5mol/L,the single-photon excited fluorescence of 1 is in the green region with a peak at 519nm and chromophore 2 in the blue region with a peak at 476nm.The very strong frequency-upconverted fluorescence emission with the central wavelength at 520 and 485nm 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.更多还原
