Materials Design and Synthesis Using Molecular Kinetic and Biphase Control

技术上有用的材料的关键结构-性能关系首先起源于原子或分子的胚胎集体组装的成核阶段，其次是不同的有机/无机纳米相的组织，形成有时在建筑上复杂的复合结构。本研究针对这两个基本过程：动力学控制的原子和分子组装，以及使用界面动力学来控制复合结构的结构、电光性质、热输运和稳定性。本文将对三种材料的合成、改性、结构表征和结构-性能关系的研究进行具体研究：(1)具有可调纳米结构尺寸和物理性能的纳米相电光和磁性材料；(2)介观（15- 2000a）结构双相复合材料和多孔材料；(3)活性骨架多孔相。一个持续的目标是发展构建具有非线性活性或导电框架的分子筛或介孔相的方法，这些框架可能与分子吸附物可逆地结合。这项研究的主要意义在于对三维复合材料和多孔相的纳米结构设计有了基本的了解。这些材料的潜在技术应用包括空气分离、催化、具有高机械强度、柔韧性的复合材料和

9520971 Stucky The key structure-property relationships of technologically useful materials have their origins first at the nucleation stage in the embryonic collective assembly of atoms or molecules, and secondly in the organization of distinct organic/inorganic nanophases to form sometimes architecturally elaborate composite configurations. This research is directed towards these two fundamental processes: kinetic controlled atomic and molecular assembly and the use of interface dynamics to control structure, electro-optic properties, thermal transport, and stability in composite structures. The synthesis, modification, structural characterization, and study of structure-property relationships will be specifically investigated for three types of materials: (1) nanophase electrooptic and magnetic materials with tunable nanostructure dimensions and physical properties; (2) meso (15-200 0A)-structured biphase composites and porous materials; and (3) active framework porous phases. A continuing goal is to develop the methodology for constructing molecular sievelike or mesoporous phases with nonlinear active or conducting frameworks that might reversibly interface with molecular adsorbates. %%% The primary significance of this research is in the development of a basic understanding of the nanostructural design of 3-dimensional composite and porous phases. The potential technological applications of these materials include air separation, catalysis, composite materials with high mechanical strength, flexibility, and
