novel structures and functionalities. In this work, we focused on the direct and efficient synthesis of a new type of AIEgens, imidazo[1,5-a]pyridicne derivatives, via iodine mediated cascade oxidative Csp2–H or Csp–H amination route from phenylacetylene or styrenes under mild conditions. The resulted compounds showed excellent AIE characteristics with tunable maximum emissions, attractive bioimaging
聚集诱导的发光致发光剂(AIEgens)的广泛应用激发了具有新颖结构和功能的AIEgens的产生。在这项工作中,我们着重于通过碘介导的级联氧化Csp 2 -H或Csp-H胺化路线从苯乙炔或苯乙烯在以下条件下直接和有效地合成新型AIEgens,咪唑并[1,5- a ]吡啶鎓衍生物。温和的条件。所得化合物显示出优异的AIE特性,具有可调节的最大发射量,有吸引力的生物成像性能以及潜在的抗炎活性,在材料,生物学,医学和其他相关领域具有广阔的应用前景。
