An AB -type monomer comprised of a calix[4]pyrrole skeleton and alternating bis-carboxylate units is reported and used for the construction of a novel supramolecular hyperbranched polymer based on anion recognition ability of calix[4]pyrrole. H-, DOSY-NMR spectroscopy, viscosity measurements, and dynamic light scattering techniques are used for the characterization of the supramolecular hyperbranched polymer exhibiting thermo-, pH-, and chemical responsiveness, as well as concentration dependent morphology tune as inferred from electron microscopy analyses. The present study enriches the field of supramolecular polymers with a new construction motif, building block, and provides a simple approach for the fabrication of smart polymer material with multi-responsiveness and -morphologies.
一种由杯[4]吡咯骨架和交替的双羧酸单元组成的 AB 型单体被报道，并用于构建一种新型超支化聚合物，该聚合物基于杯[4]吡咯的阴离子识别能力。使用 H-、DOSY-NMR 光谱、粘度测量和动态光散射技术对超支化聚合物进行表征，该聚合物表现出热、pH 和化学响应性，以及从电子显微镜分析推断出的浓度依赖性形态调谐。本研究通过使用新的构建基元和构建基元丰富了超分子聚合物领域，并提供了一种用于制造具有多响应性和多种形态的智能聚合物材料的简单方法。
