Synthesis and Characterization of Preceramic Precursors

这项少数族裔研究启动计划拨款将使William Quintana博士能够建立一个项目，研究陶瓷材料BN和B4C的分子前体。这项工作的目的是发现新的合成路线，以有效地生产预陶瓷材料。制备并研究了单取代炔基硼嗪。这些化合物将被聚合并通过核磁共振光谱进行表征。随后它们将被分解成BN。这个项目的支持将使威廉·昆塔纳博士能够建立一个研究项目，研究某些含有硼化合物的聚合物，这些化合物可以分解成陶瓷材料氮化硼。这种化合物由于其物理性质而具有相当大的商业价值。新的、更有效的制备途径对化学工业很重要。

This Minority Research Initiation Planning Grant will enable Dr. William Quintana to establish a program studying the molecular precursors to the ceramic materials BN and B4C. The object of the work is to discover new synthetic routes for the efficient production of preceramic materials. Monosubstituted alkynylborazines will be prepared and studied. The compounds will be polymerized and charactierized by NMR spectroscopy. Subsequently they will be decomposed into BN. %%% Support from this program will enable Dr. William Quintana to establish a research program investigating certain polymer containing boron compounds which can be decomposed into the ceramic material boron nitride. This compound has considerable commerical importance because of its physical properties. New, more efficient routes to its preparation are important to the chemical industry.
