The metal complex [(tpy)(Mebim-py)Ru(II)(S)](2+) (tpy = 2,2' : 6',2''-terpyridine; Mebim-py = 3-methyl-1-pyridylbenzimidazol-2-ylidene; S = solvent) is a robust, reactive electrocatalyst toward both water oxidation to oxygen and carbon dioxide reduction to carbon monoxide. Here we describe its use as a single electrocatalyst for CO(2) splitting, CO(2) → CO + 1/2 O(2), in a two-compartment elect...

Two porous organic cages with different thermodynamic polymorphs were induced by co-solvents to interchange their crystal packing modes, thus achieving guest-mediated control over solid-state porosity. In situ crystallography allows the effect of the co-solvent guests on these structural interconversions to be understood.

In the title compound, [Co(C(19)H(13)ClN(3)O)(2)]NO(3)·2CH(3)OH, the central Co(III) atom in the cation is surrounded by two tridentate ligands in a distorted octa-hedral fashion by four N and two O atoms. Classical O-H⋯O hydrogen bonds link both methanol solvent mol-ecules with the nitrate anion.

Abstract Supercritical fluids are alternatives to conventional harmful organic compounds. In the case of supercritical fluid extraction, CO2 is most common solvent and can be advantageously modified with small contents co-solvents like ethanol ethyl acetate. The rigorous estimation tracer diffusion coefficients (D12) solutes in mixtures (CO2 + co-solvent) requires their individual D12 values pu...

Solution-processed quasi-2D perovskites are promising for stable and efficient solar cells because of their superior environmental stability compared to 3D tunable optoelectronic properties. Changing the number inorganic layers (n) sandwiched between organic spacers allows tuning bandgap. However, narrowing phase distribution around a specific n-value is challenge. In-situ UV–vis–NIR absorption...

The solvothermal reaction of Co(NO(3))(2) and 2,4,6-tris(4-pyridyl)-1,3,5-triazine in dimethyl-formamide/ethanol mixed solvent afforded the title coordination polymer, [Co(NO(3))(2)(C(18)H(12)N(6))](n), in which the Co(II) atom is seven-coordinated by pyridyl groups of three different ligands and two chelating nitrate anions. The complex displays a nano-sized porous metal-organic framework that...

The conformational preference of a [2]rotaxane system has been examined by molecular dynamics simulations. The rotaxane wheel consists of two bridged binding components: a cis-dibenzo-18-crown-6 ether and a 1,3-phenyldicarboxamide, and the penetrating axle consists of a central isophthaloyl unit with phenyltrityl capping groups. The influence of solvation on the co-conformation of the [2]rotaxa...

Specifically designed co-solvent mixtures are an efficient way to enhance the kinetics of enzyme-catalyzed reactions without compromising enzyme stability; among them, several deep eutectic solvents have emerged as exciting for biocatalytic reactions. DESs nature allows one tailor enzyme-co-solvent interactions by using constituents diverse functional groups. In this work, influence co-solvents...

Porous liquid zeo-PLs, a novel class of solvent, provide more efficient CO 2 separation from CH 4 and economical alternative over the current Genosorb solvent dissolution technology. Current technologies by solvents suffer either high regeneration costs or low selectivity/capacity solvent. Dispersing ca. 12.5 wt% -selective zeolite rho solid into commercial capture Genosorb® converts it porous ...
