Minimalistic 2-(oxazolinyl)-phenols substituted with different electron-donating and -withdrawing groups as well as 1,2,5-chalcogenadiazole-annulated derivatives thereof were synthesized and investigated in regard to their emission behavior in solution as well as in the solid state. Depending on the nature of the incorporated substituent and its position, emission efficiencies were increased or diminished
合成了被不同给电子和吸电子基团取代的简约 2-(恶唑啉基)-苯酚及其 1,2,5-硫属二唑环化衍生物,并研究了它们在溶液和固体中的发射行为状态。根据引入的取代基的性质及其位置,发射效率会增加或减少,从而产生 AIE 或 ACQ 特性。单晶分析揭示了 J 型和 H 型包装基序以及迄今为止未描述的以酮形式分离的基于 ESIPT 的荧光团。
