摘要
合成了16种2,2-二苯并(口恶)唑衍生物,测定了化合物的熔点、红外光谱、紫外吸收光谱、荧光发射光谱以及荧光量子产率,与1,4-二(苯并(口恶)唑1′,3′-基-2′)苯和1,4-二(苯并(口恶)唑-1′,3′-基-2′)乙烯衍生物进行了比较,讨论了它们之间光谱特性的差异.
Sixteen of 2, 2'-bisbenzoxazole derivatives were synthesized, 13 of them are new compounds. Their m. p. , IR, UV absorption spectra, fluorescence emission spectra, fluorescence quantum efficiencies and laser conversion efficiencies of the compounds were determined. 2,2'-Bisbenzoxa-zolyl derivatives were compared with l,4-bis(1',3'-benzoxazolyl-2')benzene derivatives and E-1,2-bis( l',3' benzoxazolyl-2')ethene derivatives and the difference of their spectra properties were also discussed.
