series of boron ketoiminate derivatives that exhibited clear aggregation‐induced emission (AIE) characteristics (in THF: ΦPL≤0.01; in the solid state: ΦPL=0.30–0.76) were prepared by the reactions of 1,3‐enaminoketone derivatives with boron trifluoride–diethyl etherate. The structures and optical properties were investigated by UV‐visible spectroscopy, photoluminescent (PL) spectroscopy, and X‐ray
该显示清晰的聚集诱导的发射(AIE)特性的系列硼酮亚胺衍生物(在THF中:Φ PL ≤0.01;在固态:Φ PL = 0.30-0.76)通过1,3-烯胺酮衍生物的反应制备的用三氟化硼-乙醚乙醚。通过紫外可见光谱,光致发光(PL)光谱和X射线单晶测量研究了结构和光学性质。这些结果表明,AIE特性源自具有硼氮(BN)键的硼螯合环的分子运动。此外,通过氮原子上取代基的空间位阻可控制光学性质。
