Six novel asymmetric 1,3,4-oxadiazole derivatives containing naphthalene and stilbene units have been efficiently synthesized and characterized by FT-IR, (1)H NMR, (13)C NMR, mass spectrometry and elemental analysis. The UV-vis absorption maximum wavelength, fluorescence excitation wavelength, fluorescence emission wavelength and fluorescence quantum yield were measured in dilute tetrahydrofuran solution
高效合成了六种新型的含萘和二苯乙烯单元的不对称1,3,4-恶二唑衍生物,并通过FT-IR,(1)H NMR,(13)C NMR,质谱和元素分析对其进行了表征。在稀四氢呋喃溶液中测量UV-vis吸收最大波长,荧光激发波长,荧光发射波长和荧光量子产率。还研究了溶剂作用。这些化合物的HOMO和LUMO水平通过密度泛函理论(DFT)(B3LYP,6-31G(*))方法和循环伏安法计算。它们发出明亮的紫光到蓝光,具有高的荧光量子产率(0.23-0.94)和大的斯托克斯位移(53-102 nm)。这些化合物具有较高的HOMO水平(-5.03至-5.17 eV)和合适的带隙,表明它们可能有益于空穴注入。
