NSF Young Investigator: Metal Silicides and Catalytic Formation Polysilanes

这个NSF青年研究者奖在无机，生物无机和有机化学计划支持研究金属硅化物博士。美国田纳西大学诺克斯维尔分校化学系的薛教授说。 强调两个领域：金属硅化物和聚硅烷合成路线的开发，以及固态有机金属反应机理的研究。 关于第一个主题，将制备不含环戊二烯或类似配体的早期过渡金属甲硅烷基络合物;这种类型的化合物很少。 这些化合物将用于开发金属硅化物和聚硅烷的新路线，这些金属硅化物和聚硅烷可用于电子设备。 四氢硅烷也将用于在化学气相沉积条件下形成金属硅化物。 在第二个领域，将研究烷基化合物与膦的固-气反应。 研究将集中在反应过程中影响固态结构保留的因素。 橡树岭国家实验室的仪器将用于一些结构测定。 这项工作的影响，合成多相催化剂。

This NSF Young Investigator award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research on metal silicides by Dr. Ziling B. Xue of the Chemistry Department, University of Tennessee at Knoxville. Two areas are emphasized: development of synthetic routes to metal silicides and polysilanes, and investigation of the mechanism of solid state organometallic reactions. On the first topic, early transition metal silyl complexes which do not contain cyclopentadiene or analogous ligands will be prepared; very few compounds of this type are known. These compounds will be used to develop a new route to metal silicides and polysilanes, which are useful for electronic devices. Tetrahydrosilane will also be used to form metal silicides under chemical vapor deposition conditions. In the second area, solid-gas reactions of alkyl compounds with phosphines will be studied. Research will focus on the factors affecting retention of solid state structure during reaction. Instrumentation from Oak Ridge National Laboratory will be used for some of the structural determinations. This work has implications for synthesis of heterogeneous catalysts.
