摘要

本文介绍了以 B═N 和 B-O 连接为特征的新型含硫无机-有机杂化聚合物。砜、亚磺酰亚胺和亚砜被用作硫核单位。事实证明，类似的亚磺酰亚胺并不适用，因此产生了一种前所未有的副产品。芳基溴硼烷是 B═N 和 B-O 连接的起始材料。对每种聚合物的低分子量类似物进行了研究。最后，降解研究表明，硫单元可通过 pH 值变化再生，这表明新材料可用于药物释放项目。

Sulfur-Based Building Blocks in BN- and BO-Doped Inorganic–Organic Hybrid Polymers

New sulfur-containing inorganic–organic hybrid polymers featuring B═N and B–O linkages are described. Sulfones, sulfoximines, and sulfoxides have been used as sulfur core units. An analogous sulfilimine proved unsuitable leading to an unprecedented side product. Aryl bromoboranes served as starting materials for the B═N and B–O linkages. For each polymer, the respective low-molecular-weight analogues were studied. Finally, degradation studies showed that the sulfur units can be regenerated by pH changes suggesting the new materials to be applicable in drug release programs.

期刊介绍： Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
