The 1D array of electron donor–acceptor chromophoric organic molecules is of paramount importance for photovoltaic, catalytic and optoelectronic applications. Herein, we report coordination driven 1D arrays of an electron-donor guest (fluorene, carbazole, dibenzofuran, and dibenzothiophene) and o-phen chelator as an acceptor in a Zn-based porous coordination polymer, {[Zn(o-phen)(ndc)]·DMF} (PCP-1). All the guest-encapsulated PCPs were characterized by performing single-crystal structure determinations and showed emission driven by charge transfer. Exciton binding energies were calculated and correlated with electron-donating capabiliities of the guest molecules. [ABSTRACT FROM AUTHOR]

We delineate the growth and stabilization of ultra-small (2–3 nm) {Cu3(BTC)2(H2O)2·xH2O} MOF nanoparticles on a 2D layered aminoclay template. The composite shows significant CO2 uptake (5.35 mmol g−1 at 298 K, 1 bar; 46% higher than pristine bulk MOF), superior CO2 separation efficiency from CO2/N2 and CO2/CH4 mixtures and higher catalytic proficiency for chemical fixation of CO2 into cyclic carbonates.

In recent times, significant attention has been paid to the development of functional coordination polymer gels (CPGs) from rationally designed low molecular weight gelators (LMWGs) and metal ions. Coordination of metal ions to LMWGs provides an opportunity to emulate metal based redox, optical, electronic and magnetic properties in soft CPG materials. The metal–LMWG interactions allow controlled growth of CPGs with different nanostructures such as fibers, tubes, rings, ribbons and vesicles. Furthermore, the nanoscale periodicity of metal ions and LWMGs in CPGs is of paramount importance for different optoelectronic applications. The easy processability and dynamic nature of CPGs are explored for application in diverse fields, including drug-delivery, gas storage, optoelectronics, chemo-sensing, self-healing, etc. Also, by taking advantage of dynamic metal–ligand coordination bonds various stimuli-responsive multi-functional CPGs are developed. In this feature article, we cover important examples of newly developed CPGs, which show potential applications in different fields. [ABSTRACT FROM AUTHOR]

A novel porous anionic MOF {[Mg3(ndc)2.5(HCO2)2(H2O)][NH2Me2]⋅2H2O⋅DMF} (1) having exchangeable dim ethyl amine cations in 1D channels has been synthesized and characterized. Through cation exchange, 1 manifests bimodal functionality, being a turn-off sensor of CuII on one hand, and a selective sensitizer of EuIII emitting intense pure red emission on the other.

Hybrid nanocomposites of graphene oxide (GO) with ZIF-8 exhibit tunable nanoscale morphology and porosity, both determined by the GO content, coordination modulation being responsible for such properties. These materials also give rise to high CO2 storage capability and can be used as precursors to prepare GO@ZnS nanocomposites. [ABSTRACT FROM AUTHOR]

Metal mediated in situC–N coupling between 4,4′-azobipyridine and disodium-trans-glutaconate at room temperature has formed a new multifunctional linker Z-dhpewhich subsequently self-assembles with Zn(ii) or Cd(ii) resulting in a chiral or an achiral metal–organic framework, respectively, depending on its different coordination modes.

A bimetallic pillared-layer coordination framework {[Mn3(bipy)3(H2O)4][Cr(CN)6]2·2(bipy)·4(H2O)}nhas been constructed using a cyanometallate anion ([Cr(CN)6]3−) and an organic linker (4,4′-bipyridyl) that provides high heat of hydrogen adsorption (∼11.5 kJ mol−1) and shows guest dependent magnetic modulation.
