Abstract

Two zinc(II)-based coordination polymers, namely, {[Zn₂L₂(bmib)]·DMA}_n (1) and {[ZnL(bipd)]}_n (2). (H₂L = 5-{(anthracen-9-ylmethyl)amino}isophthalic acid, bmib = 1,4-bis(2-methyl-imidazol-1-yl)butane, bipd = 3,5-bi-1H-imidazol-1-ylpyridine, DMA = N,N-dimethylacetamide), were synthesized by a hydrothermal method. Single-crystal X-ray diffraction analysis showed that in 1 and 2, the carboxylic acid ligand possesses abundant coordination models: 1 shows a tangled one-dimensional (1D) chain structure and through weak interactions forms a 2D structure, while 2 possesses a two-dimensional (2D) structure. Fluorescence experiments showed that 1 and 2 can be used as good fluorescent sensors for selectively detecting SA with a detection limit of 0.87 and 27.03 μM, respectively. Notably, SA can be further identified via the naked eye, which has significant potential for practical applications. In addition, mechanism studies showed that detection of SA by 1 and 2 is attributed to a competition absorption mechanism.

两种锌基配位聚合物作为水杨醛荧光传感器，具有高灵敏度和选择性

采用水热法合成了两个锌（II）基配位聚合物{[Zn2L2(bmib)]·DMA}n(1)和{[ZnL(bipd)]}n (2). （H2L = 5-{（蒽-9-甲基）氨基}对苯二甲酸，bmib = 1,4-双（2-甲基-咪唑-1-酰基）丁烷，bipd = 3,5-双- 1h -咪唑-1-酰基吡啶，DMA = n， n-二甲基乙酰胺）。单晶x射线衍射分析表明，在1和2中，羧酸配体具有丰富的配位模型：1为缠结的一维（1D）链结构，通过弱相互作用形成二维结构，2为二维（2D）结构。荧光实验表明，1和2可以作为选择性检测SA的良好荧光传感器，检测限分别为0.87和27.03 μM。值得注意的是，SA可以通过肉眼进一步识别，具有很大的实际应用潜力。另外，机理研究表明，1和2对SA的检测是一种竞争吸收机制。
