新型间苯二酚杯芳烃硫脲衍生物对阴离子的识别

通过间苯二酚杯芳烃连续三步反应, 以较高产率合成了分子中连有8个和12个硫脲端基的间苯二酚杯芳烃的酰胺衍生物. 用紫外可见光谱法研究了两个代表性化合物4,6,10,12,16,18,22,24-八6-(苯基硫脲基)-己氨甲酰基甲氧基]-2,8,14,20-四苯基杯4]间苯二酚芳烃(THBC)和4,6,10,12,16,18,22,24-八2-(苯基硫脲基)-1-甲基乙基-1-氨甲酰基甲氧基]-2,8,14,20-四苯基杯4]间苯二酚芳烃(TPBC), 对各种阴离子(AcO^－, H₂PO₄^－, HSO₄^－, H₂PO₄^2－, C₁₂H₂₅-C₆H₄-SO₃^－, Cr₂O₇^2－, B₄O₇^2－, Cl^－, Br^－)的识别性能, 结果表明它们对AcO^－, H₂PO₄^－, HSO₄^－等阴离子有较好的配位作用, 能形成1∶3的配合物.

Syntheses and Anion Recognition of Novel Calix[4]resorcinarene Thiourea Derivatives

Four novel calix4]resorcinarene-based amide derivatives containing eight or twelve terminal phenylthiourea groups were smoothly synthesized in three steps from the corresponding calix4]- resorcinarenes in good yields. Their structures were characterized by elemental analysis and ¹H NMR, IR, UV spectra. The binding properties of the two representative THBC and TPBC for anions with UV-vis spectra were studied. They showed better recognition ability for AcO^－, H₂PO₄^－ and HSO₄^－ anions to form 1∶3 stoichiometric complexes.
