摘要: 本文设计合成了新型的氟硼荧(氟硼二吡咯,BODIPY)功能化的间苯二咪唑配体5。利用刚性二咪唑配体的配位作用及氟硼二吡咯的荧光特性,配体5与Ag(I) 络合后成功地获得了具有优良发光特性的配位聚合物凝胶,并通过TEM、SEM、荧光光谱等检测手段对该凝胶的结构和性能进行了表征。研究显示,银离子的加入并未影响荧光团的发射波长及荧光强度,使得配体的荧光特性在凝胶状态下得以保持。这一研究结果是本课题组刚性二咪唑-Ag(I)配合物凝胶的又一成功范例,使得采用类似方法构筑其它不同类型的配位聚合物发光凝胶成为可能。

Abstract: A novel BODIPY functionalized imidazole derivative 5 has been designed and synthesized. Utilizing coordination of rigid bisimidazole moiety and photoluminescence properties of BODIPY, we have achieved formation of a fluorescent coordination polymeric gel, which has been characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and photoluminescence spectroscopy. The results show that the emission wavelength and fluorescence intensity of fluorophore were not affected by the adding Ag+ and photoluminescence properties of ligand 5 in the gel phase were retained. This result is another successful example of our research in rigid bisimidazole-Ag(I) coordination gel, which offers an opportunity for forging versatile fluorescent coordination polymeric gels.
