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.

这项少数民族研究启动计划赠款将使 威廉·昆塔纳博士建立了一个研究 陶瓷材料BN和B4C的分子前体。的 工作的目的是发现新的合成路线， 高效生产陶瓷前体材料。单取代 炔基环硼嗪将被制备和研究。化合物 将聚合并通过NMR光谱表征。 随后，它们将被分解为BN。 %%% 该计划的支持将使William Quintana博士能够 建立一个研究计划，研究某种聚合物 含硼化合物，可分解成 陶瓷材料氮化硼。这种化合物具有相当大的 由于其物理特性，具有重要的经济意义。新的， 更有效的制备方法对 化工专业化
