Crystal growths in gel medium of lanthanide-based coordination polymers with 2,5-dihydroxyterephthalate (dhbdc2−) as ligand lead to two different crystal structures depending on the lanthanide ion. Lanthanide-based that crystallize these structural type have respective chemical formulas [Ln2(dhbdc)3(H2O)12·6H2O]∞ Ln = La-Nd, and [Ln2(dhbdc)3(H2O)8·6H2O]∞ Sm-Yb plus Y. Only Nd-based Yb-based exh...

meta-Ethynylpyridine polymers bearing metal coordination sites associate with alkyl glycoside guests to show induced circular dichroism (ICD) bands. The addition of a Cu(II) ion changed the intensity or the sign of these ICD bands. The changes suggested chiral helicity amplification or inversion of the polymers by Cu(II)-mediated cross-linking at the coordinating side chains.

Reactions in the solid state are at the core of crystal engineering as they can result in new crystalline phases that are not always accessible by traditional solution methods. The work of Brammer and co-workers [Wright et al. (2015), IUCrJ, 2, 188-197] represents a clear example of this potential as applied to the synthesis of a silver-phenazine coordination polymer.

Five new silver camphorimine complexes of general formula [Ag(NO3)(Y)L] were synthesized and fully characterized using spectroscopic and analytical techniques. The structure of [Ag(NO3)(OC10H14NC6H4NC10H14O)] () was analyzed using single crystal X-ray diffraction, showing that it arranges as a coordination polymer formed by sequential Ag(NO3) units bridged by the bi-camphor ligand (). The antim...

This review focuses primarily on the past 10 years of our development of multifunctional coordination polymers with 1D, 2D and 3D structures employing low-temperature and cost-effective hydrothermal and solvothermal methods. The effects of the experimental conditions and parameters on the crystal formation and phase separation, including temperature and pressure, reaction pH, solvent and compos...

Recent developments in polymerizations within the nanochannels of porous coordination polymers (PCPs) are covered in this tutorial review. The characteristic features of PCPs are regular structures, controllable channel sizes and shapes, a designable surface functionality, and flexible frameworks, which can be utilized for precision polymer synthesis and specific polymer confinement. This revie...
