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.
