| 摘 要： | 设计合成了一个四苯基乙烯衍生物Model-TPE，该化合物具有典型的聚集诱导发光（AIE）特性。1HNMR、质谱以及高效液相色谱研究表明，有氧条件下Model-TPE经紫外光照射发生关环反应，生成二苯基取代菲衍生物，取代和未取代苯环侧关环反应得到异构体产物，提出了光氧化关环反应机理。本工作对TPE衍生物在发光及传感领域的应用有一定的指导意义。

| Abstract: | A tetraphenylethene derivative (Model-TPE) was design and synthesized. The photophysical studies demonstrate that Model-TPE showes typical AIE (aggregation induced emission) character. Model-TPE proceeded photocyclization upon UV irradiation in the presence of oxygen, which has been approved by 1HNMR, MALDI-TOF MS and HPLC studies. The photocyclization at substitute and non-substitute phenyl side gave two isomers. The mechanism of photocyclization of Model-TPE was discussed. The experiment results shown here provide important information for potential applications of tetraphenylethene derivatives as emitting and sensing materials. |
