    Synthesis and Metal Ion Complexation Studies of Proton-Ionizable Calix[4]azacrown Ethers in the 1,3-Alternate Conformation
    摘要:
    A series of novel N-chromogenic calix[4]arene azacrown ethers were synthesized as selective extractants of potassium ion. 1,3-Alternate calix[4]arene azacrown ethers were prepared by reacting 25,27-dipropyloxy-26,28-bis(5-chloro-3-oxapentyloxy) calix[4]arenes with p-toluenesulfonamide in the presence of potassium carbonate. The coupling reaction of calix[4]arene azacrown ether with 2-hydroxy-5-nitrobenzyl bromide in the presence of triethylamine in THF gave the chromogenic calix[4]arene azacrown ether in moderate yield. These compounds show high potassium selectivity, over other metal ions as shown by two-phase extraction, bulk liquid membrane, and H-1 NMR studies on a ligand-metal complex. It is assumed that the OH of the chromogenic group attached on nitrogen can assist the complexation by encapsulation of the metal.

    以香豆素为荧光单元的基于杯[4]芳烃的荧光化学传感器:合成,表征,离子结合性质和分子建模
    摘要:
    已经合成了一系列圆锥形和1,3-交替构型的基于杯[4]芳烃的荧光化学传感器,结合了乙二醇单元作为结合位点和香豆素作为荧光探针。这些化合物经设计具有不同的取代基,杯芳烃单元的构象和空间拥挤。开链乙二醇部分是柔性的,因此它们可以在空间中定向以与金属离子有效地相互作用。这些氟离子载体的离子结合研究已使用大量金属离子进行,离子识别事件通过荧光和吸收光谱法进行监测。在Fe 3+和Cu 2+存在下,发射强度发生大幅度淬灭,而在Ca存在下,发射强度增强2+表明这些金属离子与离​​子载体牢固结合。这些金属离子的络合作用还可以从UV-Vis光谱变化中看出。通过ESMS分析已确认形成的复合物的组成(1∶1)。从荧光滴定数据已经评估了与强相互作用金属离子的结合常数。已经进行了DFT计算,以发现杯状离子载体的金属结合位点,并且在这些情况下,前沿分子轨道分析已使与金属离子络合时观察到的荧光行为合理化。

    ring and without tert-butyl at the upper rim (2) exhibits complexation with K+, Rb+, Ba2+ and weak interaction with Na+. Binding constants with these metal ions have been determined by NMR titration. Molecular modeling studies performed by a molecular mechanics force field (MMFF94) using the Monte Carlo search method and DFT calculations predicted the observed higher selectivity for sterically crowded

  • Chromogenic Azo-Coupled Calix[4]arenes

    Novel 1,3-alternate calix[4]azacrowns having an azo chromophoric pendent group were synthesized, and their 1,3-alternate conformations were confirmed by X-ray crystal structure. In view of the hypsochromical UV band shifting upon cation complexation, azo-coupled calix[4]azacrown-5 (3) showed the most selective shifting with alkali and alkaline metal ions. In addition, 3 revealed K+ ion selectivity not only due to the size comparability between the K+ ion and the azacrown-5 loop but also due to a significant K+-pi interaction between the two aromatic rings and the K+ ion. The UV band shifting is also dependent on the lipophilicity of the species of counteranion used.

    A series of calix[4]arene-based fluorescent chemosensors in cone and 1,3-alternate conformations have been synthesised incorporating ethylene glycol units as binding sites and coumarin as fluorescent probe. These compounds have been designed with variation in substituents, conformations of the calixarene unit and steric crowding. The open chain ethylene glycol moieties are flexible so that they can
