A zinc-based one-dimensional (1D) coordination polymer ([Zn(Hmpca)(tfbdc)(HO)], Zn-ODCP) has been synthesized and characterized by spectroscopic and physicochemical methods, single-crystal X-ray diffraction, and thermogravimetric analysis (Hmpca = 3-methyl-1H-pyrazole-4-carboxylic acid; Htfbdc = 2,3,5,6-tetrafluoroterephthalic acid). Zn-ODCP shows blue luminescence in the solid state. When Zn-ODCP acts as an anode material for lithium ion batteries, it exhibits a good cyclic stability and a higher reversible capacity of 300 mAh g at 50 mA g after 50 cycles. The higher capacity may be mainly ascribed to the metal ion and ligand all taking part in lithium storage. Searching for electrode materials of lithium ion batteries from 1D metal coordination polymers is a new route.
一种基于锌的一维（1D）配位聚合物（[Zn(Hmpca)(tfbdc)(HO)]，Zn-ODCP）已通过光谱和物理化学方法、单晶X射线衍射以及热重分析进行了合成和表征（Hmpca = 3-甲基-1H-吡唑-4-羧酸；Htfbdc = 2,3,5,6-四氟对苯二甲酸）。Zn-ODCP在固态下呈现蓝色发光。当Zn-ODCP用作锂离子电池的负极材料时，在50 mA g的电流密度下循环50次后，它表现出良好的循环稳定性和300 mAh g的较高可逆容量。较高的容量可能主要归因于金属离子和配体都参与了锂存储。从一维金属配位聚合物中寻找锂离子电池的电极材料是一条新途径。
