A crystal engineering rationale has been exploited to
generate
a series of CuII coordination polymers namely [{Cu(μ-L1)(SO4)(H2O)3}·H2O]∝ CP1, [{Cu(μ-L1)2(H2O)2}F·2H2O]∝ CP2 [{Cu(μ-L1)2(H2O)2}Cl·H2O]∝ CP3 and [{Cu(μ-L1)2(H2O)2}Br·H2O]∝ CP4 derived from N, Ń-(3-pyridyl)
m-phenyleneurea (L1) capable of gelling aqueous solvents
(DMF/water); in situ crystallization of CP1 has been
exploited to separate SO42‑ anion selectively
from a complex mixture of oxo anions (SO42–, NO3–, ClO4–, CF3SO3–). While the gels
are characterized by optical-, scanning electron microscopy and rheology,
structure–property (gelation, as well as anion separation)
correlation has been attempted by using single crystal- and powder-X-ray
diffraction data.
运用晶体工程原理，成功合成了一系列CuII配位聚合物，包括 [{Cu(μ-L1)(SO4)(H2O)3}·H2O]∝ CP1、[{Cu(μ-L1)2(H2O)2}F·2H2O]∝ CP2、[{Cu(μ-L1)2(H2O)2}Cl·H2O]∝ CP3 以及 [{Cu(μ-L1)2(H2O)2}Br·H2O]∝ CP4，这些聚合物由N, Ń-(3-吡啶基)间苯二胺（L1）制成，能够凝胶化水溶剂（DMF/水）。通过原位结晶法，CP1被用于从含有多种氧化物阴离子（SO42–、NO3–、ClO4–、CF3SO3–）的复杂混合物中选择性分离SO42‑阴离子。凝胶的表征通过光学、扫描电子显微镜和流变学方法进行，同时，通过单晶和粉末X射线衍射数据，尝试了结构-性能（凝胶化以及阴离子分离）的相关性研究。
