中文摘要：

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,将配体5与Ag（Ⅰ）络合后获得了具有优良发光特性的配位聚合物凝胶,并通过TEM、SEM和荧光光谱等手段对该凝胶的结构和性能进行了表征.结果表明,银离子的加入并未影响荧光团的发射波长及荧光强度,即配体的荧光特性在配合物状态下仍得以保持,此现象与配位聚合物凝胶具有较强荧光特性的结果一致.

英文摘要：

Coordination chemistry as a rational design route toward functional supramolecular metallogels is currently gaining intensive attention,because the presence of the metal ions would endow the gel unique functionalities such as photo-electronic,catalytic and redox properties.However,there are few reports regarding the photoluminescence properties of coordination polymeric gels to date.In this paper,a novel boron-dipyrromethene（BODIPY） functionalized imidazole derivative 5 was designed and synthesized.Utilizing coordination of rigid bisimidazole moiety and photoluminescence properties of BODIPY,we achieved formation of a fluorescent coordination polymeric gel,which was 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 are not affected by the adding Ag＋,that is,photoluminescence properties of ligand 5 in the coordinated phase are retained,which consistent with that of coordination polymeric gel.This result offers an opportunity for forging versatile fluorescent coordination polymeric gels.
