  硫杯芳烃的离子识别：硫杯[4]芳烃-双冠[n]醚对碱金属和重金属离子的结合

  摘要：

  通过提取实验检查了两种硫杯 [4] 芳烃-双冠 [n] 衍生物（n = 5 和 6）的结合特性。测定所得配合物在甲醇中的稳定性常数。用硫原子取代桥接 CH2 基团导致碱金属离子的萃取和络合水平大大降低，但不影响冠醚系列内的选择性。从thiacalix[4]arene-bis-crown[n]醚到它们的calix[4]arene-bis-crown[n]对应物时，与重金属离子的配合物的稳定性没有显着变化；因此，无法得出关于这些阳离子与硫原子之间可能相互作用的明确结论。

  A mononuclear nickel(II) and copper(II) complexes with a metal:ligand ratio of 1:2 for H2L were also synthesized. The mononuclear cobalt(III) complex of H2L has been isolated with L′ = pyridine, together with chlorine as an axial ligand. In addition, a cobalt(III) complex containing the BF2+ bridge macrocycle was synthesized using a precursor hydrogen-bridged cobalt(III) complex via the template effect

  Four different types of new ligands Ar[COC(NOH)R](n) (Ar=biphenyl, n = 1 H(2)L(1); Ar=biphenyl, n = 2 H(4)L(2); Ar=diphenylmethane, n = 1 H(2)L(3); Ar=diphenylmethane, n = 2 H(4)L(4); R=2-amino-4-chlorophenol in all ligands) have been obtained from 1 equivalent of chloroketooximes Ar[COC(NOH)Cl](n) (HL1-H2L4) and 1 equivalent of 2-amino-4-chlorophenol (for H(2)L(1) and H(2)L(3)) or 2 equivalent of 2-amino-4-chlorophenol (for H(4)L(2) and H(4)L(4)). (Mononuclear or binuclear cobalt(II), nickel(II), copper(II) and zinc(II) complexes were synthesized with these ligands.) These compounds have been characterized by elemental analyses, AAS, infra-red spectra and magnetic susceptibility measurements. The ligands have been further characterized by (1)H NMR. The results suggest that the dinuclear complexes of H(2)L(1) and H(2)L(3) have a metal:ligand ratio of 1:2; the mononuclear complexes of H(4)L(2) and H(4)L(4) have a metal:ligand ratio of 1:1 and dinuclear complexes H(4)L(2) and H(4)L(4) have a metal:ligand ratio of 2:1. The binding properties of the ligands towards selected transition metal ions (Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Pb(II), Cd(II), Hg(II)) have been established by extraction experiments. The ligands show strong binding ability towards mercury(II) ion. In addition, the thermal decomposition of some complexes is studied in nitrogen atmosphere

  Extraction constants for lead picrate, PbPic(2), with 18-crown-6 ether (L) from aqueous solutions at a narrow range of ionic strength (I) into eleven diluents were determined at 298 K by AAS measurements. These constants were defined as K-ex=[PbLPic(2)](0)/([Pb2+][L](0)[Pic(-)](2)) and K-ex +/-=[PbLPic(+)](0)[Pic(-)](0)/([Pb2+][L](0)[Pic(-)](2)), where the subscript "o" denotes the organic phase (or diluent). The ratio, K-ex/K-ex +/-, gave an ion-pair formation constant for PbLPic(o)(+) + Pic(o)(-)=PbLPic(2,o) at the averaged value of ionic strength (I-o) of the organic phase. A plot of log K-ex +/- versus log k(D.pc) yielded a straight line with the slope of 2.1 in a series of the diluents employed; K-D,K-Pic refers to an apparent distribution constant of Pic- between the aqueous and organic phases and its values were experimentally determined. The slope indicated that K-ex +/- is mainly controlled by the square of K-D,K-PIc when a thermodynamic cycle is assumed. The extraction constant based on the cycle was expressed as K-ex +/-=(K-D,K-Pic)(KD,MKML,orgK1,org)-K-2, where KD,MKM,L,orgK1,org denotes the product of other component equilibrium-constants. Moreover, the relation of log K-D.Pic=alog (I-o/I) + b was experimentally found at a approximate to 1 and then an example of b was expressed theoretically. It was shown that Pb(II) can be separated from mixtures with Cd(II) in unit operation. (C) 2014 Elsevier B.V. All rights reserved.
