Regioselectivity in organic reactions is an important goal for chemists. In addition to increasing yields of desired products, separation costs are minimized. Enzymes are the most efficient regioselective catalysts, however, they are not hardy enough for most industrial processes. Zeolites, with their molecular-sized channels and cavities, have many of the properties of enzymes. They are able to select specific molecules according to size, orient these molecules into a particular conformation and supply reactive sites. The research plan for this proposal is to design and synthesize ZSM-5 zeolite crystals with internal catalytic interfaces separating areas of high and low Al concentration. The research work will also establish physical techniques, concentrating on NMR, to demonstrate the presence and evaluate the quality of these interfaces.

在有机反应中的区域选择性是一个重要的目标， 化学家 除了增加所需产物的产率外， 分离成本被最小化。 酶是最有效的 然而，对于区域选择性催化剂，它们不够哈代， 大多数工业过程。 Zeolites，它们的分子大小 通道和空腔具有酶的许多特性。 它们能够根据大小选择特定的分子， 将这些分子定向成特定的构象 活性位点 本提案的研究计划是设计和合成 具有内催化界面的ZSM-5沸石晶体 将高铝浓度区和低铝浓度区分开。 研究 工作还将建立物理技术，集中在 NMR，以证明存在和评价质量 这些接口。
