rings. The trinuclear core is surrounded by three pairs of BFHQ ligands with offset π–π stacking, showing propeller-like molecular structure. The aggregation behavior of Zn(AcO)2 and the ligand 4 in solution was investigated by UV–vis. The luminescence properties of compound 5 were investigated by UV–vis and fluorescence spectra at room temperature. The experimental results show that the complex 5 emits
一种新型的2-取代的8-羟基喹啉配体(E)-2- 2- [3- [3,5-双(三氟甲基)苯基]乙烯基} -8-羟基喹啉(4,BFHQ)的用途,其特征在于EIMS,1 H NMR光谱,元素分析和FTIR光谱能够分离具有式Zn 3(BFHQ)6的三聚体Zn(II)配合物(5,方案1)。X射线结构分析表明,5具有三核芯,由四个8-羟基喹啉环桥接。三核核心被三对BFHQ配体包围,它们具有π-π堆积,显示出螺旋桨状分子结构。Zn(AcO)2和配体4的聚集行为溶液中的残留量通过UV-vis研究。通过紫外可见光谱和室温下的荧光光谱研究了化合物5的发光特性。实验结果表明,该配合物5分发出黄色在553纳米发光(λ EM,最大值在DMSO溶液中,在610纳米)(λ EM,最大值在固体状态)。进行热重分析以检查热稳定性。
