A new microporous organic polymer (PCB?NH2) has been synthesized based on amine functionalized carbazole derivative by oxidative coupling polymerization with anhydrous FeCl3. Polymer PCB-NH2 exhibits microporous nature with a BET surface area of 542.4 m2 g?1, and shows moderately high CO2 and C2H2 adsorption capacities, 51.6 cm3 g?1 (10.3 wt%), 58.4 cm3 g?1 (7.5 wt%) at 278 K, 1 atm, respectively. Remarkably, at 278 K, the predicted IAST selectivities of PCB-NH2 are 16.7?5.8 for a CO2/CH4 (5:95 v/v) gas mixture and 34.3?21.0 for a C2H2/CH4 (50:50 v/v) gas mixture at pressures varying from 0 to 1 atm, respectively. More interesting, PCB-NH2 displays higher CO2/CH4 selectivity than its matrix polymer PCB. The isosteric heats of CO2 adsorption (Qst) for PCB-NH2 and PCB further indicate that the amine group may facilitate the interaction between the polarizable CO2 molecules and the polymer by local dipole?quadrupole interactions, subsequently favors selective gas separation for these gas molecules. The high selectivity of CO2/CH4 and C2H2/CH4 makes PCB-NH2 possible candidate for future natural gas upgrading and acetylene purification.

Electric Literature of 21436-03-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a patent, introducing its new discovery.

Although a variety of fluorescence based chemosensors have been utilized for selective detection of Zn2+, pyridoxal containing simple Schiff bases still remained less explored. Here, we combine pyridoxal hydrochloride and 1,2-diaminocyclohexane to generate a new sensor molecule, H4PydChda [5-Hydroxymethyl-4-({2-[5-hydroxymethyl-2-methylpyridin-3-hydroxy-4-ylethylene)-amino]-cyclohexylimino}-methyl-2-methylpyridin-3-ol]. Chemosensor H4PydChda exhibits selective turn-on type response in presence of Zn2+ in ethanol-water mixture at physiological pH. Appreciable fluorescence enhancement occurs upon addition of Zn2+ to H4PydChda as a result of inhibited C[dbnd]N isomerisation and excited state intramolecular proton transfer (ESIPT) leading to efficient chelation enhanced fluorescence (CHEF). The relevant properties, including reversibility, life time measurements and detection limit have been determined for the sensor system. The experimental and theoretical supports in terms of 1H and 13C NMR spectroscopy and DFT/TDDFT study are provided to establish the binding mode of H4PydChda to Zn2+. H4PydChda was employed as a sensor for detection of Zn2+ in Human gastric adenocarcinoma (AGS) cells. Moreover, the resulting probe-Zn2+complex shows convincing phosphatase activity (kcat = 21.59 s?1), opening a promising avenue for further research.

The solubility data of each system were obtained by using cloud point method. For evaluation of extraction ability of the solvents used in this work, the distribution coefficients and separation factors were calculated and 1-pentanol was demonstrated to be very suitable. Besides, Othmer-Tobias and Hand correlation equations were applied to check the consistency of the tie-line data. Furthermore, NRTL and UNIQUAC models were used to correlate the experimental data with all the RMSD values less than 2.57%.

Unsymmetric Schiff base complexes have attracted more attention in recent years due to their diverse effects in catalytic reactions. Due to their high dissymmetry, unsymmetric metallosalen complexes are harder to prepare than symmetric ones. This means that X-ray crystallographic structural determination is sometimes unavailable, so their absolute configurations are determined by circular dichroism (CD) spectroscopy instead. Herein, some quadridentate unsymmetric metallosalen nickel(II) complexes were synthesized and their structures were characterized by CD spectra. An empirical rule for assignment of the absolute configurations of tetra-coordinated pseudo-planar Ni(II) complexes was put forward. Furthermore, a fingerprint was found to judge whether the metallosalen complexes are symmetric or unsymmetric.

Salen metal complexes incorporating two chiral BINOL moieties have been synthesized and characterized by X-ray crystallography. The X-ray structures show that this new class of Ni-BINOL-salen catalysts contains an unoccupied apical site for potential coordination of an electrophile and naphthoxides that are independent from the Lewis acid center. These characteristics allow independent alteration of the Lewis acidic and Bronsted basic sites. These unique complexes have been shown to catalyze the Michael reaction of dibenzyl malonate and cyclohexenone with good selectivity (up to 90% ee) and moderate yield (up to 79% yield). These catalysts are also effective in the Michael reaction between other enones and malonates. Kinetic data show that the reaction is first order in the Ni·Cs-BINOL-salen catalyst. Further experiments probed the reactivity of the individual Lewis acid and Bronsted base components of the catalyst and established that both moieties are essential for asymmetric catalysis. All told, the data support a bifunctional activation pathway in which the apical Ni site of the Ni·Cs-BINOL-salen activates the enone and the naphthoxide base activates the malonate.

The systematic reactions of a family of tetradentate pyridyl/imine and quinolyl/imine racemic or enantiopure Schiff bases with Ni(NO3)2 or Ni(ClO4)2 in the presence of sodium azide yielded, as a function of the starting racemic, chiral or achiral base, a set of chiral, meso or achiral complexes. In all cases, the compounds consist of two NiII cations linked by a double azido bridge in its end-on coordination mode. All the dimers exhibit a mesocate supramolecular structure and one of them, the unprecedented mix of helicate and mesocate in 2:1 ratio. The transition from mesocate to helicate conformation has been reached by tuning the flexibility of the central spacers of the Schiff bases and the size of the substituents. Electronic circular dichroism (ECD) studies have been performed for two pairs of enantiomers and interpreted by means of DFT calculations. Susceptibility measurements show a ferromagnetic coupling between the NiII cations mediated by the end-on azido bridges.
