New Phosphorus and Boron Based Polymer Systems

该奖项由化学部门的特别项目办公室和材料合成与加工倡议下的材料研究部门颁发。该研究涉及新型磷基和硼基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（亚氨基硼烷）和聚（硼氮烯/磷腈）。准备合适的起始单体。活性磷中心作为聚合物主链的一部分或作为悬垂基团的加入有望赋予这些材料有用的化学、物理和电学性质。主要目标是制备基于B-N、P=N和/或B-N-P-N键的可处理的、特性良好的聚合物的第一个例子。具有不饱和B-N和P-N键的聚合物可能表现出新的电子性质，并且应该用作B-N和P-N陶瓷组合物的前体。

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.
