  摘要：

  报告了一种合成四乙炔乙烯 (TEE) 和四乙烯乙烯 (TVE) 杂化物的分子结构的一般合成方法。该合成允许控制制备许多以前难以接近的结构，包括在四个支臂中的每一个上具有不同取代基的例子。大多数取代的 TVE-TEE 杂化物被发现是比未取代的对应物更强大的化合物，增强了它们在导电材料和器件中的应用前景。它们参与周环反应级联，导致 sp 3富多环，得到证实。还建立了利用 TEE-TVE 杂化物作为更大的无环、直通/交叉共轭碳氢化合物骨架的构件。芳基取代的 TEE、TVE 及其杂化物是荧光的，其中一些表现出聚集诱导的发射增强。定义和解释了结构要求，为荧光探针和有机发光二极管的应用奠定了基础。
