Abstract

Star-shaped polymers with the calix[8]arene core and poly(2-isopropyl-2-oxazoline) and poly(2-isopropyl-2-oxazoline)–poly[3-(2-oxazoline)propionic acid] block copolymer arms at various ways of attaching blocks to the core are synthesized by ring-opening cationic polymerization. Luminescent labels are introduced by the esterification of carboxyl groups by diazomethane derivatives. In order to obtain interpolymer complexes luminescently labeled poly(methacrylic acid) and poly(acrylic acid) are synthesized. The resulting polymers are characterized by the methods of molecular hydrodynamics and optics. Interpolymer complex formation in the aqueous solutions of the polymers is studied by polarized luminescence. It is shown that the chemical structure of the polyoxazoline fragment and the way of its addition to the core influence the structural and dynamic characteristics of the interpolymer complexes with polycarboxylic acids and their stability.

摘要

带有杯[8]芳烃芯和聚（2-异丙基-2-恶唑啉）和聚（2-异丙基-2-恶唑啉）-聚[3-（2-恶唑啉）丙酸]嵌段共聚物臂的星形聚合物通过开环阳离子聚合合成以各种方式将嵌段连接到核上的方法。通过重氮甲烷衍生物将羧基酯化来引入发光标记。为了获得互聚物配合物，合成了发光标记的聚（甲基丙烯酸）和聚（丙烯酸）。所得的聚合物通过分子流体动力学和光学方法表征。通过偏振发光研究了在聚合物的水溶液中互聚物配合物的形成。
