摘要
以杯[4]芳烃为平台,构筑结构与识别性能独特的杯[4]芳烃衍生物是有机超分子化学的重要研究领域.本文中,杯[4]二芳胺基衍生物3与异硫氰酸苯酯反应得到开链的二硫脲基杯[4]衍生物4,产率为95%.化合物3与等物质的量对二异硫氰酸苯酯反应得到二硫脲基桥连杯[4]衍生物5,产率为80%.与过量的对二异硫氰酸苯酯反应则以产率为82%得到化合物6.化合物6进一步与水杨酰肼反应得到含硫脲基的多重氮杂杯[4]衍生物7,产率为75%.紫外光谱配合实验表明新主体分子4-7对测试的4种有机染料分子(橙黄Ⅰ、茜绿素、维多利亚蓝和亚甲基蓝)均显示出较强的配合能力,配合常数的数量级达10^5,配合比为1∶1.开链结构与多重胺基和芳基结构更有利于配位包合能力的提高.
By using calix[4]arene as platform, the construction of calix[4]arene derivatives with unique structures and binding properties is the important research field in organic supramolecular chemistry. In this paper, the chain-opening calix[4]arene bi-thiourea derivative 4 was synthesized by reacting calix[4]arene bi-aromatic amino derivative 3 with phenyl isothiocyanate in yield of 95%. Treating compound 3 with p-phenylene diisothiocyanate(molar ratio=1∶1) gave bridging calix[4]arene bi-thiourea derivative 5 in yield of 80%. Treating compound 3 with excess p-phenylene diisothiocyanate afforded calix[4]arene thiourea derivative 6 in yield of 82% and was further converted to multiple-azo calix[4]arene derivative 7 by reacting compound 6 with salicylyl hydrazine in yield of 75%. The experiments of UV titration spectra for four tested dyes(orange Ⅰ, alizarin green, victorial blue and methylene blue) showed that compounds 4-7 possessed excellent complexation abilities with 1∶1 ratios for complexation and 10-5 magnitudes for the association constants. The chain-opening structure, more amino groups and more aromatic groups were favorable for the improvement of complexation abilities.
