Cooperative Phenomena and Domain Switching Processes in Organic Inclusion Compounds

这篇题为《有机包合化合物中的协同现象和域切换过程》的论文的重点是对固体中协同相互作用的分子理解，特别是在应用各向异性应力（铁弹性）下进行宏观畴重定向的一系列包合化合物的设计、合成和表征。该研究计划将在分子水平上解决控制晶体中畴转换过程的因素，铁弹性的机制，以及速率决定步骤。由于铁弹性和铁电性密切相关，强调铁弹性性质的合作决定因素应该为铁电材料的畴切换过程提供重要的见解。铁电包合物的设计和合成将提供新的材料，由于它们的客体分子重定向的快速时间尺度，应该使它们成为快速开关电光材料的高度兴趣。＊＊＊

9619191 Hollingsworth The focus of this proposal entitled Cooperative Phenomena and Domain Switching Processes in Organic Inclusion Compounds is on a molecular understanding of cooperative interactions in solids, and in particular on the design, synthesis and characterization of a series of inclusion compounds that undergo macroscopic domain reorientation under applied anisotropic stress (ferroelasticity). The research program will address on a molecular level what it is that controls domain switching processes in crystals, what are the mechanisms of ferroelasticity, and what the rate determining steps are. Because ferroelasticity and ferroelectricity are so closely related, the emphasis on cooperative determinants of ferroelastic properties should provide important insights into the domain switching processes in ferroelectric materials. %%% The design and synthesis of ferroelectric inclusion compounds will provide new materials, which because of their fast timescale for guest molecular reorientation, should make them of high interest as rapidly switching electrooptical materials. ***
