Five coordination polymers (CPs), namely {[Zn(L)(ip)·H₂O]₈}_n (1), {[Zn(L)(2-ntp)]·H₂O}_n (2), {[Zn(L)(tdc)·2H₂O]₂}_n (3), {[Cd(L)(tp)·H₂O]·3.43H₂O}_n (4) and [Cd(L)(5-mip)]_n (5) (L = 1,3-bis(benzimidazol-1-yl)-2-propanol, H₂ip = isophthalic acid, 2-H₂ntp = 2-nitroterephthalic acid, H₂tdc = 2,5-thiophenedicarboxylic acid, H₂tp = terephthalic acid and 5-H₂mip = 5-methylisophthalic acid) have been hydrothermally synthesized. 1 exhibits a 3D 4-connected coordination framework with the rarely (8⁶)-hxg/p topology. 2 is 2D (6,3) network incorporating [Zn₂(L)₂] loops, and further extended into a 3D supramolecular framework by O–H⋯O hydrogen bondings. 3 possesses a three-fold interpenetrated diamond network. 4 also forms a 2D (6, 3) layer, which is extended to a 3D supramolecular framework by the aromatic stacking interactions. 5 displays a 3,5-connected 3D 3,5T1 framework with a point symbol of {4²·6⁵·8³}{4²·6}. Further, 1 and 2 exhibit highly selectivity and sensitivity for luminescence sensing of acetone/Cr₂O₇²⁻ anions in aqueous solution, respectively.

五个配位聚合物（CP），即{[Zn（L）（ip）·H ₂ O] ₈ } _n（1），{[Zn（L）（2-ntp）]·H ₂ O} _n（2） ，{[Zn（L）（tdc）·2H ₂ O] ₂ } _n（3），{[Cd（L）（tp）·H ₂ O]·3.43H ₂ O} _n（4）和[Cd（ L）（5-mip）] _n（5）（L = 1,3-双（苯并咪唑-1-基）-2-丙醇，H ₂ ip =间苯二甲酸，2-H ₂ ntp = 2-硝基对苯二甲酸， H ₂ tdc = 2,5-噻吩二甲酸，H水热合成了₂ tp =对苯二甲酸和5-H ₂ mip = 5-甲基间苯二甲酸。图1展示了一个3D 4连接的协调框架，该框架很少（8 ⁶）-hxg / p拓扑。2是包含[Zn ₂（L）₂ ]环的2D（6,3）网络，并通过O–H⋯O氢键进一步扩展为3D超分子框架。3具有三重互穿的钻石网络。图4还形成2D （6、3）层，其通过芳族堆积相互作用而延伸至3D超分子框架。5显示3,5-连接的3D3,5T1框架，其点符号为{4 ² ·6 ⁵ ·8 ³ } {4 ² ·6}。此外，1和2分别显示出对水溶液中丙酮/ Cr ₂ O ₇ ^2-阴离子的发光传感的高度选择性和灵敏度。
