摘 要:以二苯甲酮衍生物为原料,经McMurry偶联反应合成得到对称的四芳基乙烯衍生物,其结构经1HNMR、13CNMR、MS及元素分析确证。新分子的聚集诱导发光性能均优于四苯乙烯。在聚集态,荧光寿命都超过3 ns,其中TPE-4OBz达到5.93 ns。新分子都具有较高的固体荧光量子产率,其中TPE-4Me可达45.54%。以上研究说明取代基的引入提高了分子的聚集诱导发光性能,为进一步的应用研究提供可能。单晶结构显示,TPE-4Me具有螺旋桨构型,为发光机理研究提供模型。New symmetrical tetra-aryl ethene derivatives were designed and synthesized by McMurry coupling reaction from benzophenone derivatives.The structure and purity of all the new compounds were confirmed by 1H,13CNMR and MS associated with elemental analysis.All the new compounds showed aggregation-induced emission property which were better than tetraphenylethene.The PL lifetime of all aggregated samples were lengthened to more than 3 ns.The PL lifetime of TPE-4 OBz can reach to 5.93 ns.The solid fluorescence quantum yields were improved,which was 45.54%of TPE-4 Me.These results indicated that the different substitutions improved the aggregation-induced emission property,which provided the possibility of application.Single crystal of TPE-4 Me is propeller configuration,which provides a model for the research of aggregation-induced emission mechanism.
