  环烷基环状硫脲的合成和阴离子选择性络合

  摘要：

  合成了具有邻位，间位，间位和间对位三种环烷结构的环状硫脲衍生物和套索型硫脲，并研究了它们的阴离子结合能力。使用（1）H NMR光谱通过滴定法测量DMSO-d（6）中受体与几种阴离子之间的络合缔合常数。除间-对环芳基外，所有受体均表现出与磷酸二氢根阴离子的选择性结合，该结合力强于无环参考化合物。与不具有第三结合位点的环状受体相比，套索型受体甚至更牢固地结合阴离子。

  [GRAPHICS]This paper reports the electroscopic and electrochemical properties of [ 2 + 2] pyromellitic diimide-based cyclophane 1 as well as acyclic N, N'-bis( 2-methoxybenzyl) pyromellitic diimide 2 and the clathrate compounds formed by 1. Compound 1 was synthesized by direct cyclocondensation. Its structure was determined by an X-ray crystallographic analysis of a single crystal obtained by recrystallization from DMF. The intramolecular charge-transfer interactions of 1 and 2 were characterized by UV/vis spectroscopy and MO calculations. The UV/vis spectra showed that the tail of a longer wavelength absorption of both 1 and 2 reached the visible region. MO calculations ( B3LYP/6-31G*) showed that the HOMO and LUMO orbitals of 1 and 2 substantially localize in the xylyl and pyromellitic diimide moieties across the methylene linker, respectively. The X-ray crystallographic analyses demonstrated that single crystals grown from a mixture of 1 and alpha-naphthol and a mixture of 1 and beta-naphthol were the clathrate compounds with 1D and 2D supramolecular assemblies, respectively, which are formed by a combination of hydrogen-bonding and charge-transfer interactions. From the cyclic voltammetry measurements, both 1 and 2 showed reversible reduction processes, and the reduction potential observed at - 1.09 V vs Ag/Ag+ for 2 split into two potentials at - 1.01 and - 1.14 V for 1. The addition of alpha- and beta-naphthol induced a decrease in the potentials due to the diradical anion of 1 and radical anion of 2 by about 80 mV, and their reduction processes were reversible.

  Cyclic thiourea derivatives having three different types of cyclophane structure, ortho-meta, meta-meta, and meta-para, and a lariat-type thiourea, were synthesized, and their anion-binding ability was examined. The association constants for the complexation between the receptors and several anions in DMSO-d(6) were measured by the titration method using (1)H NMR spectroscopy. All receptors, except
