Highly dispersed Ni nanoparticles have been successfully immobilized by the zeolitic metal-organic framework ZIF-8 via sequential deposition-reduction methods, which show high catalytic activity and long durability for hydrogen generation from hydrolysis of aqueous ammonia borane (NH(3)BH(3)) at room temperature. 相似文献

The preparation and characterization of luminescent neutral Au(12) shuttle-like complexes is reported which shows a cyclic framework consisting of twelve gold(i) ions arranged in a closed ring via non-covalent Au(i)Au(i) interactions to give a chiral D(2) symmetrical structure. 相似文献

When the reaction conditions are deliberately controlled by the pH, two different polynuclear manganese complexes, (Δ, Λ)-{Mn3(phen)2 (CH3COO)6} (1) and [Mn(phen)Cl2]n (2) (phen = 1,10-phenanthroline), have been synthesized from the same raw materials. The structural analyses show that 1 has a structure formed by neutral chiral linear trinuclear molecules, while 2 has a structure consisting of one-dimensional infinite chains. A study of the temperature dependent magnetic susceptibilities reveal that 1 is an antiferromagnetically coupled trimer molecule while 2 shows ferromagnetic interactions within the chain. 相似文献

Rapid photoresponse (1.0-8.0 min) through fluorescence "turn-on" signaling displayed by a novel Schiff base (L) creating "gate lock" via intramolecular C-H···N interaction in photoisomerized product (L') has been described. Coordination chemistry of pre- and postirradiated species demonstrated a drastic change in the reactivity which has been supported by NMR, HRMS, UV-vis, emission, electrochemical, and complexation studies. 相似文献

Crystalline metal-organic framework (MOF) nanosheets have been fabricated via top-down delamination from bulk crystals of a layered MOF, {Zn(TPA)(H(2)O)·DMF}(n) (MOF-2), and characterized by Tyndall scattering, scanning electron microscopy and atomic force microscopy measurements. The delaminated MOF-2 nanosheets exhibit remarkable amine intercalation property and reversible amine exchangeability. 相似文献

This paper describes the synthesis and blocking activities of twelve new isoindolinone- and isobenzofuranone-containing phenoxylalkylamines as potent α(1)-Adrenoceptor antagonists. These compounds were synthesized in moderate to good yields starting from 3,4-dimethylphenol, and characterized with (1)H-NMR, MS, IR and elemental analysis. Their blocking activities toward α(1)-Adrenoceptors were evaluated on isolated rat anococcygeus muscles. The results indicated that these compounds were very strong in blocking α(1)-Adrenoceptors, and most of them exhibited activities that were comparable to that of known potent α(1)-Adrenoceptor antagonist 1-(2,6-dimethylphenoxy)-2-(3,4-dimethoxyphenylethylamino)propane hydrochloride (DDPH). 相似文献
