Green Chemistry and Modern Technology 总被引:4,自引:0,他引:4
The basic principles, approaches, and early achievements of green chemistry are considered. The definition of green chemistry as a branch of chemistry that studies the laws of passing of chemical reactions and the properties of substances participating in such reactions, with the aim of acquiring basic knowledge that provides a basis for designing chemical technologies that eliminate (sharply curtail) the use and production of materials that pose a risk to the environment. 相似文献

ESR measurements have been made on complexes formed by copper(II) with [12]anS4, [13]anS4, iso-[14]anS4, and [18]anS6; they show intramolecular reduction for the central ion by electron transfer from the donor sulfur atoms, and free cation-radicals are formed in solution. The covalency parameter 2 indicates that the copper-sulfur bonds are mainly covalent. The electronic structures are analogous to those of the active centers in copper-bearing blue proteins.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 25, No. 6, pp. 737–742, November–December, 1989. 相似文献

New luminescent heterometallic complexes of Eu3+ and Zn2+ were synthesized: Zn2Eu(NO3)(Piv)6(L)2 (Piv is pivalate anion, L = MeCN (1), 2,3-lutidine (2), 2,2′-bpy (3)) and [Zn2(Piv)3(2,2′-bpy)2][ZnEu(NO3)3(Piv)3(2,2′-bpy)] (4). In the case of 2,2′-bpy, the order of mixing of the reagents ([Zn(Piv)2] n , Eu(NO3)3·6H2O, and 2,2′-bpy) affects the composition of the final reaction product: the reaction of [Zn(Piv)2] n and Eu(NO3)3·6H2O (in the ratio Zn : Eu = 3 : 1) in MeCN affords complex 1 and the subsequent addition of 2,2′-bpy (Zn : L = 1 : 1) affords complex 3. Complex 4 is formed in the reaction of [Zn(Piv)2] n and 2,2′-bpy (Zn : L = 1 : 1) in MeCN followed by the addition of Eu(NO3)3·6H2O (Zn : Eu = 3 : 1). The luminescence spectra of compounds 1–4 (Zn : Eu = 3 : 1) exhibit metal-centered luminescence of Eu3+. The most efficient ligand-antenna is 2,2′-bpy, which is due to the optimum position of the triplet level of this ligand. 相似文献

The temperature dependences of the magnetic susceptibilities for the complexes [Fe2III MIIO(p-NitPhCOO)6]∙MeCN (M = Co, Ni, p-NitPhCOO–= p-benzoatenitronyl nitroxide radical, MeCN = acetonitrile) revealed the existence of antiferromagnetic exchange coupling among
the metal ions in the trinuclear units, as well as between these units and the free radicals in the crystal lattices of the
complexes. 相似文献

The effect of the chemical structure of metal–organic framework compounds (MOF) (the presence of coordination-unsaturated
metal ions, the nature of the metal ions, the presence of electron donor and electron acceptor groups in the ligands) on the
ability of such compounds to sorb hydrogen is examined. It is shown that the macroscopic parameters (the surface area and
pore size) make a major contribution to the adsorption of hydrogen while the chemical structure of the MOF plays a subsidiary
role by determining the structural characteristics of the adsorbent. 相似文献

It was shown that the reaction of the trinuclear complex [FeFe2O(CH3CO2)6(H2O)3]·2H2O with thiourea in tetraethylene glycol leads to the formation of nanoparticles of thiospinel Fe3S4, the size of which depends on the reaction conditions. It was established that the formed thiospinel particles exhibit superparamagnetic
characteristics. It was shown that the size of the nanoparticles has an effect on their magnetic characteristics. 相似文献
