Synthesis in the Study of Carbon Networks

这项研究的重点是双重的。 第一，新颖的两阶段过程 将为碳网络的筹备工作开发。 初始 步骤涉及多价单体单元在聚合物中的组织/取向。 晶格 第二步由聚合和交联 单体在其晶格位置上。 让人联想到沸石的材料 应导致。 第二个重点领域是金刚石薄膜的生长。 小的有机基质将被用来探测假设的碳 纳入机制。 有了这个更新奖，有机和 高分子化学计划是支持博士肯S。 宾夕法尼亚州立大学化学系的费尔德曼说。 费尔德曼教授将把工作重点放在设计和合成 共价连接的周期性一维、二维和三维网络， 主要由碳组成。 这些系统有潜力解决 在分离和催化技术中的具体目标。 此外该 化学气相沉积（CVD）过程中碳的掺入机理 将追求金刚石膜生长。 这些知识将提供一个 为后续的基质相容性研究奠定了基础， 可以引发膜表面改性。

The foci of this research are two-fold. First, a novel two stage process will be developed for the preparation of carbon networks. The initial step involves organization/orientation of polyvalent monomer units in a lattice. The second step consists of polymerizing and crosslinking the monomers in their lattice positions. Materials reminiscent of zeolites should result. The second area of emphasis is on diamond film growth. Small organic substrates will be used to probe hypothesized carbon incorporation mechanisms. With this renewal award, the Organic and Macromolecular Chemistry Program is supporting the research of Dr. Ken S. Feldman of the Department of Chemistry at Pennsylvania State University. Professor Feldman will focus his work on the design and synthesis of covalently linked, periodic one-,two- and three-dimensional networks, composed mainly of carbon. Theses systems have potential to address specific goals in separations and catalysis technology. In addition, the mechanism of carbon incorporation during Chemical Vapor Deposition (CVD) diamond film growth will be pursued. This knowledge will provide a foundation from which subsequent studies on substrate compatibility and film surface modification can be initiated.
