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.

这项研究的重点有两个方面。首先，将开发一种新的两阶段工艺来制备碳网络。初始步骤涉及晶格中多价单体单元的组织/取向。第二步是单体在晶格位置上的聚合和交联。应该会产生让人联想到沸石的材料。第二个重点领域是金刚石薄膜的生长。将使用小型有机底物来探索假想的碳结合机制。通过这个续展奖项，有机和高分子化学项目支持宾夕法尼亚州立大学化学系的Ken S.Feldman博士的研究。费尔德曼教授将专注于设计和合成共价连接的周期性一维、二维和三维网络，这些网络主要由碳组成。这些系统有可能解决分离和催化技术中的特定目标。此外，还将探讨化学气相沉积(CVD)金刚石薄膜生长过程中碳掺入的机理。这一知识将提供一个基础，在此基础上可以启动对基片兼容性和薄膜表面改性的后续研究。
