New Phosphorus and Boron Based Polymer Systems

该奖项由化学部特别项目办公室和材料合成和加工倡议下的材料研究部颁发。本研究涉及新型含磷和含硼聚合物的合成和表征，包括聚磷二烯、聚碳磷腈、聚磷氮化物、聚亚胺硼烷和聚硼氮烯/磷氮烯。将制备合适的起始单体。活性磷中心作为聚合物主链的一部分或作为侧基的引入有望赋予这些材料有用的化学、物理和电学性质。主要目标是制备第一批基于B-N、P=N和/或B-N-P-N键的易处理、表征良好的聚合物。具有不饱和B-N和P-N键的聚合物可能会显示出新的电子性质，并有望用作B-N和P-N陶瓷组合物的前驱体。

This award is made in the Special Projects Office of the Chemistry Division and the Division of Materials Research under the Materials Synthesis and Processing Initiative. The research involves the synthesis and characterization of new phosphorous and boron-based polymers including poly(phosphadienes), poly(carbophosphazenes), poly(phosphanitrides), poly(iminoboranes) and poly(borazene/phosphazenes). Suitable starting monomers will be prepared. The incorporation of reactive phosphorous centers either as part of the polymer backbone or as pendant groups is expected to impart useful chemical, physical and electrical properties to these materials. A major objective is to prepare the first examples of tractable, well-characterized polymers based on the B-N, P=N, and/or B-N-P-N linkages. %%% Polymers with unsaturated B-N and P-N bonds may exhibit novel electronic properties and should be useful as precursors to B-N and P-N ceramic compositions.
