  直径杯[4]亚芳基二醌的合成，构型和氧化还原性质

  摘要：

  通过在有机溶剂中用Tl（NO 3）3 ·3H 2 O氧化25,27-二烷氧基杯[4]芳烃2a-e，合成了几种在相对位置（对位）具有醌部分的杯[4]芳二醌3a-e。。这些化合物的构象性质已通过X射线晶体学确定为固态，而在溶液中通过可变温度动态NMR确定。我们发现，杯[4]芳烯二醌3a-e比母体25,27-二烷氧基杯[4]芳烃2a-e更柔软在溶液中，取决于烷氧基的空间体积，倾向于呈现两种不同的固态部分锥体结构。循环伏安法表明，杯[4]亚芳基醌3a-e的氧化还原性质取决于其构象性质。

  Two fluorescent probes 1 and 2 are developed that are capable of measuring two different metal ions under basic and acidic conditions, respectively. These probes contain a fluorophore, whose two forms are interconvertible in acidic and basic solutions and have the potential to measure the concentration of each metal ion in a mixture of caesium–potassium or sodium–potassium ions, respectively.

  compounds (1 and 2) having a propylene moiety in their structure and for this named calix[4]arene-propylene-crown-6. The structures of compounds 1 and 2 were elucidated by NMR in solution and for 1 also by X-ray diffraction studies in the solid state. Association constants (Ka) in CHCl3 of the two novel calix-crowns were measured and pointed out a plateau selectivity towards alkali metal ions which was not

  气相的从头算计算表明，在1,3-二-异-丙氧基杯[4]芳烃-冠-6的聚醚桥中，乙烯被丙烯部分取代可能导致Cs + / K增强+选择性，这在核废料处理中尤为重要。因此，我们合成了两种新颖的在其结构中具有丙烯部分的杯[4] arene-crown-6化合物（1和2），并以此命名为杯[4] arene-丙烯-冠-6。化合物的结构1和2通过NMR在溶液中，并阐明1也是在固态通过X射线衍射研究。关联常数（Ka）在两个新的杯形树冠的CHCl 3中进行了测量，并指出了对碱金属离子的平台选择性，这是分子模型计算无法预测的。这些结果表明，溶剂分子和抗衡阴离子在此类离子载体的结合中起着重要作用。

• Synthesis, Complexation, and Membrane Transport Studies of 1,3-Alternate Calix[4]arene-crown-6 Conformers: A New Class of Cesium Selective Ionophores

  1,3-Dialkoxycalix[3]arene-crown-6 ionophores (4a-d) are obtained in the fixed 1,3-alternate conformation in 63-85% yield by the reaction of the corresponding 1,3-dialkoxycalix[4]arenes 3a-d with pentaethylene glycol ditosylate in CH3CN in the presence of Cs2CO3. The corresponding cone conformer of the diisopropyl derivative (6) was synthesized via selective demethylation of the 1,3-dimethoxycalix-crown (2a) and subsequent dialkylation. Extraction experiments with alkali picrates reveal a strong preference of ligands 4 for Cs+. Thermodynamic parameters obtained for the complexation of 4a show that the high stability constant in MeOH (log beta = 6.4 +/- 0.4) is reflected mainly in the large -Delta H-c value of 50.2 +/- 0.2 kJ . mol(-1). The entropy of complexation (T Delta S-c = -15 kJ . mol(-1)), less negative than for other crown ethers, is explained in terms of preorganization of 4a. The X-ray structure of the cesium picrate . 4a complex shows clearly that the cation is positioned between the two aromatic rings with short Cs-C distances of 3.49 and 3.69 Angstrom, respectively. H-1 MMR spectroscopy confirms this type of structure in solution. Ligands 4 incorporated in supported liquid membranes transport Cs+ cations with a high preference over Na+. By the application of an anion gradient, traces of Cs+ can be removed (greater than or equal to 99.8%) from acidic solutions (pH = 0) that contain 4 M of NaNO3.
