摘要:
聚集态诱导发光(AIE)材料由于克服了有机发光材料常见的聚集态荧光猝灭现象，提高了固体发光效率而引起了研究者的重视，而噻咯（Silole）是具有AIE性质的环状多烯化合物中最具代表性的一种.实验合成了一种双苯基乙烯取代的含硅杂环化合物1，１二甲基3，4二苯基2，5二苯基乙烯Silole，并利用核磁共振表征了其结构，表明为目标产物.紫外可见分光光度法测试结果表明吸收峰在380 nm处.光致发光测试显示发射峰在420 nm处，并通过改变良溶剂和不良溶剂的比例，测试了目标产物的聚集态诱导发光性质.所选用良溶剂/不良溶剂组分别为二氯甲烷/甲醇（甲苯、水）、四氢呋喃/甲醇（甲苯、水）.结果表明，该化合物在良溶剂中发光微弱，但在聚集态下具有良好的荧光性能，显示出明显的聚集态诱导发光性质.
Abstract:
Aggregationinduced emission (AIE) materials have attracted a great deal of interest as they overcome aggressioncaused quenching which is common in organic lightemission materials and improve the emission efficiency in solid state.Among the cyclic polyene compounds with AIE properties,silole is the most typical one.In this research,1,１dimethyl3,4diphenyl2,5bis(4vinylphenyl) silole was synthesized and its structure was characterized by nuclear magnetic resonance,showing that it is the target product.Its absorption peak is at 380 nm by ultraviolet spectra and its emission peak is at 420 nm by photoluminescenc spectra.AIE properties are tested by varying the ratios of good and poor solvents in PL tests.The mixed solvents are dichloromethane/methanol(water,toluene) and tetrahydrofuran/methanol(water,toluene) respectively.The preliminary results show that the compound exhibits weak emission in good solvents,but strong fluorescence in aggregates,indicating that it is an aggregationinduced emission compound.
