Solvent-induced single-crystal to single-crystal transformation of a 2D coordination network to a 3D metal–organic framework greatly enhances porosity and hydrogen uptake

Abstract

Exposure to CH(2)Cl(2) at room temperature induces single-crystal to single-crystal transformation of the 2D coordination network [Zn(2)L(DMF)(4)]·2DMF·4H(2)O to the 3D metal-organic framework [Zn(2)L(H(2)O)(2)]·xsolv via dimerization of the metal-connecting points, leading to significant enhancement in framework stability, porosity, and H(2) uptake capacity.

Vibrational–Structural Combined Study into Luminescent Mixed Copper(I)/Copper(II) Cyanide Coordination Polymers

“…These structural rearrangements through the exchange of molecular fragments or ligands have already been reported for several systems. [43,44] Finally, the luminescence properties have been evaluated through emission, excitation, and quantum yield measurements.…”

Thermally-induced single-crystal-to-single-crystal transformations from a 2D two-fold interpenetrating square lattice layer to a 3D four-fold interpenetrating diamond framework and its application in dye-sensitized solar cells

“…1−4 In the process of crystal growth 18 and post-synthetic treatment, due to the tension and shear forces produced by component 19 changes, the brittle single crystal tends to increase mosaicity and even crack into smaller and the corresponding change in dimensionality is reflected by small changes in porosity, and 28 optical and thermal stability. 1−4 In the process of crystal growth 18 and post-synthetic treatment, due to the tension and shear forces produced by component 19 changes, the brittle single crystal tends to increase mosaicity and even crack into smaller and the corresponding change in dimensionality is reflected by small changes in porosity, and 28 optical and thermal stability.…”

“…In the photoelectric transformation, 17 co-sensitization by means of multiple sensitizers including complexes would appear to be 18 more effective to improve the absorption ability of solar cell. 27 The colleagues of Lin and Wen 27 obtained SCSC transformation of the 2D coordination network to the 3D metal-organic 28 framework via dimerization of the metal-connecting points, leading to significant 29 enhancement in framework porosity. Therefore, the synthesis of co-sensitizers with 22 high dimensional and pore structures is very important.…”

“…24 It is found that complexes with 19 large surface area and interconnected molecules will help to adsorb sufficient dye and provide 20 a pathway for the transport of electrons, and further improve the photovoltaic properties of 21 DSSCs when they are used as co-sensitizers. 28 To the best of our knowledge, high dimensional 30 interpenetrating complexes as co-sensitizers are never investigated. The structural transformation of one 23 of these complexes is accompanied by SCSC manner which helps to get high dimensional 24 structure and framework porosity.…”
