| Design and synthesis of two coordination polymers for the rapid detection of ciprofloxacin based on triphenylpolycarboxylic acid ligands | |
| 摘要: 通过水热反应合成了2例配位聚合物：[Cd (H3cpbda)(2，2'-bipy)(H2O)]n(1)和[Mn (H3cpbda)(phen)(H2O)]n(2)，其中H5cpbda=5，5'-[(5-羧基-1，3-苯基)双(氧)]三间苯二甲酸，2，2'-bipy=2，2'-联吡啶，phen=菲咯啉。使用单晶X射线衍射、粉末衍射、红外光谱和热重等对2个配合物进行了表征。配合物1和2都为“V”字型的一维链，分子间通过弱的π…π堆积分别形成二维(1)和三维(2)的骨架结构。另外，将配合物1分散在水溶液中，其荧光强度表现出良好的稳定性，并且可以特异性检测尿液中的环丙沙星，检测限为1.91×10-8 mol·L-1。 | |

| Abstract: Two coordination polymers were synthesized by hydrothermal reaction, namely, [Cd(H3cpbda)(2，2'-bipy) (H2O)]n (1) and[Mn(H3cpbda)(phen)(H2O)]n (2)，where H5cpbda=5,5'-[(5-carboxy-1,3-phenyl)bis(oxy)]triisophthalic acid, 2,2'-bipy=2,2'-bipyridine, phen=1,10-phenanthroline. The two complexes were characterized by single-crystal X-ray diffraction, powder diffraction, infrared spectroscopy, and thermogravimetric analysis. Complexes 1 and 2 are “V”-shaped 1D chains, and the molecules form 2D (1) and 3D framework (2) structures through weak π…π stacking. Furthermore, complex 1 was dispersed in an aqueous solution and its fluorescence intensity demonstrated excellent stability. Complex 1 can specifically detect ciprofloxacin in urine with a detection limit of 1.91×10-8 mol·L-1. | |
