  Anion complexation by calix[4]arene–TTF conjugates

  摘要：

  Calix[4]arenes bearing tetrathiafulvalene (TTF) moieties appended to the upper rim via the amidic functions were synthesized and used for H-1 NMR and UV/Vis complexation studies towards selected anions. It was found that the complexation affinity towards H2PO4- dramatically depends on the substitution pattern of the calixarene moiety. As a result, the proximally disubstituted derivative has a complexation constant by two orders of magnitude higher than the distally disubstituted analogue. The differences between proximal and distal receptors were also documented by their behaviour during the oxidation of the attached TTF units. (C) 2011 Elsevier Ltd. All rights reserved.

  accessible calix[4]arene conformers immobilized by four propyl or isopropyl groups by Duff reaction. Propyl group led to exhaustively formylated products due to the weak steric hinderance effect. While as for the isopropoxy calix[4]arenes, with the increase of steric hinderance, 1,3-alternate conformer gave exhaustively formylated product with no alkyl group dealkylating; partial cone conformer gave the

  甲酰基被引入对位通过Duff反应固定在四个丙基或异丙​​基上的三个容易获得的杯[4]芳烃构象异构体的位置。由于弱的位阻作用，丙基基团导致了彻底的甲酰化产物。至于异丙氧基杯[4]芳烃，随着位阻的增加，1,3-交替构象异构体给出的是甲酰化产物，没有烷基脱烷基。部分圆锥构象异构体以1，3-交替构象得到四甲酰化的近端A，B-二醚；且视锥构象异构体产生三甲酰化衍生物，并伴有三个或两个直链烷基的选择性脱烷基。结果表明，起始化合物的空间位阻效应极大地影响了产物的结构。

  Calix[4]arene bearing a convergent carboxylic acid function employing the Kemp’s triacid motif exhibited a pronounced selective ionophoric behavior toward Cs+ over other alkali metal ions. The selectivities of calix[4]arene-acid for Cs+ over Rb+, K+, and Na+ ions assessed by competitive transport experiments were 7.9, 26, and 121, respectively.

  Calix[4]arene derivatives immobilised in the cone conformation and bearing p-nitrophenyl moieties appended to the upper rim via the amide functions have been synthesised and applied as anion receptors. The H-1 NMR and UV/Vis complexation studies towards selected anions proved that the complexation ability depends considerably on the substitution pattern of the calixarene core. Thus, the proximal diamide derivative has a complexation constant for H2PO4- by one order of magnitude higher than the distal analogue.(C) 2011 Elsevier Ltd. All rights reserved.
