The aim of this project is to develop an approach for conducting solid state chemical synthesis that provides the degrees of synthetic freedom of the liquid phase. The method utilizes molecules, as linear templates, to direct alignment of reactive sites using the strength and directionality of hydrogen bonds. The goals include: (1) expanding the methods to reaction homology by developing families of templates and reactants and (2) applying products of the approach for the design of a class of porous crystalline materials known as inverted metal-organic frameworks. These materials will be engineered to possess tunable pores of nanoscale dimensions lined with organic functionality. The ability to synthesize the organic building blocks of these materials in the solid state means that access to porous solids not achievable by other synthetic methods may be realized. The program seeks to integrate research ideas with education at the local, regional, and national level through events such as campus workshops that introduce students to green chemistry and materials science.Solid-state chemical techniques provide an environmentally-friendly, or 'green' alternative to synthetic processes that rely on toxic organic solvents or routes to new molecules and materials with unique properties. For example, strategies for the design of porous crystalline solids are of much interest owing to their promise to deliver materials with properties that improve upon traditional and industrially important inorganic solids such as zeolites, a class of materials i

该项目的目的是开发一种进行固态化学合成的方法，以提供液体的合成自由度。该方法利用分子作为线性模板，利用氢键的强度和方向性来指导活性中心的排列。目标包括：(1)通过开发模板和反应物家族，将方法扩展到反应同源性；(2)将该方法的产品应用于设计一类称为倒金属-有机骨架的多孔晶体材料。这些材料将被设计成具有纳米尺度的可调孔，并带有有机功能。在固态中合成这些材料的有机构件的能力意味着可以获得其他合成方法无法实现的多孔固体。该项目旨在通过向学生介绍绿色化学和材料科学的校园研讨会等活动，将研究理念与地方、地区和国家层面的教育相结合。固态化学技术为依赖有毒有机溶剂的合成过程或获得具有独特性质的新分子和材料的途径提供了一种环境友好的或说是绿色的替代方法。例如，多孔晶体固体的设计策略很受关注，因为它们承诺提供具有比传统和工业上重要的无机固体(如沸石)更好的性能的材料，沸石是一类材料
