2-氰基-3-(4-(1,2,2-三苯基乙烯基)苯基)丙烯酸乙酯(TPE-SKJ)是一种新合成的基于四苯乙烯的发光体，单晶分析表现出聚集诱导发射(AIE)等光物理现象；可逆机械致变色、溶剂致变色、有机发光二极管；水介质中的化学传感，具有很高的选择性和较低的检测限。合成材料表现出在混合水介质（水/乙腈，v/v，9/1）中传感 MnO4 的高选择性和灵敏度能力。 MnO4– 的检测限为 0.086009 µg mL–1，量子产率 (Φ) 为 11%。此外，我们在有机发光二极管（OLED）中采用TPE-SKJ材料作为发射层。该器件的最大外量子效率为 1.62%，高于基于非掺杂发光层的绿色 OLED。目前的结果将鼓励正在进行的新型刺激响应有机材料的设计研究，这些材料具有基于超分子相互作用的可切换特性，适用于多种应用。
Ethyl 2-cyano-3-(4-(1,2,2-triphenylvinyl) phenyl) acrylate (TPE-SKJ), a newly synthesized luminogen based on tetraphenylethene, with single crystal analysis exhibits photophysical phenomena such as aggregation-induced emission (AIE); reversible mechanochromic, solvatochromic, organic light emitting diode; and chemical sensing in aqueous media with great selectivity and a low limit of detection. The synthesized material demonstrates high selectivity and sensitivity capacity for sensing MnO4–in mixed aqueous media (water/acetonitrile, v/v, 9/1). The detection limit for MnO4–was found to be 0.086009 μg mL–1with a quantum yield (Φ) of 11%. Moreover, we employed TPE-SKJ material in an organic light-emitting diode (OLED) as an emissive layer. The device shows a maximum of 1.62% external quantum efficiency, higher than nondoped emitting layer-based green OLEDs. The present results will encourage ongoing research into the design of novel stimuli-responsive organic materials with switchable properties based on their supramolecular interactions for numerous applications.
