Cooperative Phenomena and Domain Switching Processes in Organic Inclusion Compounds

小行星9619191 这一建议题为合作现象和域切换过程中的有机包合物的重点是在固体中的合作相互作用的分子理解，特别是在设计，合成和表征的一系列包合物，进行宏观域重定向下施加各向异性应力（铁弹性）。 该研究计划将在分子水平上解决什么是控制晶体中的域转换过程，铁弹性的机制是什么，以及速率决定步骤是什么。 由于铁弹性和铁电性是如此密切相关，强调铁弹性性质的合作决定因素，应该提供重要的见解铁电材料的畴开关过程。 铁电包合物的设计和合成将提供新的材料，由于其快速的客体分子重新取向的时间尺度，应该使它们作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. ***
