A series of symmetric, silicon-linked organic fluorescent compounds with two electron-deficient 1,3,4-oxadiazole units were synthesized and characterized. The compounds possessed a V-shaped structure with a silicon atom, which weakened π–π stacking, promoting aggregation-induced emission. The compounds were fluorescent in both solution and solid-state thin films. The efficient fluorescent behavior
合成并表征了一系列具有两个缺电子 1,3,4-恶二唑单元的对称硅连接有机荧光化合物。这些化合物具有带硅原子的 V 形结构,削弱了 π-π 堆积,促进了聚集诱导发射。这些化合物在溶液和固态薄膜中都是荧光的。通过光学和电化学测量证实了材料的有效荧光行为。这些化合物表现出优异的热稳定性,分解温度超过 400 °C。化合物的非晶薄膜具有较高的形态稳定性。这些结果表明这些化合物可能是有前途的发光和电子传输材料。
