For the first time, a series of catechol-containing Schiff bases, tetrasubstituted at the lower rim thiacalix[4]arene derivatives in three stereoisomeric forms, , , and , were synthesized. The structure of the obtained compounds was proved by modern physical methods, such as NMR, IR spectroscopy, and HRMS. Selective recognition (K difference by three orders of magnitude) of copper (II) cation in the series of d-metal cations (Cu, Ni, Co, Zn) was shown by UV-vis spectroscopy. Copper (II) ions are coordinated at the nitrogen atom of the imine group and the nearest oxygen atom of the catechol fragment in the thiacalixarene derivatives. High thermal stable organic-inorganic copper-based materials were obtained on the base of + Cu (II) complexes.
首次合成了一系列在下缘四取代的含儿茶酚席夫碱、具有三种立体异构形式的硫杂杯[4]芳烃衍生物，即 、 和 。通过现代物理方法，如核磁共振（NMR）、红外光谱（IR）和高分辨质谱（HRMS）对所得化合物的结构进行了确证。紫外可见光谱表明，在一系列二价金属阳离子（铜、镍、钴、锌）中，该化合物对铜（II）阳离子具有选择性识别能力（K值相差三个数量级）。在硫杂杯芳烃衍生物中，铜（II）离子与亚胺基团的氮原子以及儿茶酚片段最近的氧原子配位。基于 + 铜（II）配合物制备了高热稳定性的有机 - 无机铜基材料。
