本项目将开发一系列低温地形战术合成策略。它将重点关注(1)在各种化合物中诱导混合价的拓扑策略，例如钙钛矿，离子交换阳离子可以通过拓扑策略制备混合价或进一步操纵其价；(2)已知金属阴离子阵列化合物在钙钛矿宿主体内的组装；(3)合成新的宿主材料，如层状钙钛矿，旨在利用所提出的策略；(4)开发新的综合策略。新型合成路线的发展对于发现具有优越性能的新型层状材料非常重要，这些材料对健康、能源、环境、电子和通信等各个领域的日常活动都有影响。此外，这一基础科学领域是培养未来科学家和工程师的理想培训基地

This project will develop a series of low-temperature topotactic synthetic strategies. It will focus on (1) topotactic strategies to induce mixed valency in a variety of compounds, such as the perovskites, with ion exchangeable cations that can be made mixed valent or have their valency further manipulated by topotactic methods; (2) the assembly of known compounds of metal-anion arrays within perovskite hosts; (3) the synthesis of new host materials such as layered perovskites designed to exploit the proposed strategies; and (4) the development of new synthetic strategies.%%%The development of novel synthetic routes is important to the discovery of new classes of layered materials with superior properties that have impact on everyday activities in diverse areas such as health, energy, environment, and electronic and communications. Furthermore, this area of fundamental science is an ideal training ground for educating future scientists and engineers.***
