Tetraaryladamantanes Mediating Crystallization

当有机分子结晶时，它们形成无限的、有序的三维晶格。 有时，溶剂分子包含在晶体中，特别是当结晶分子本身不能实现致密堆积时。 我们最近观察到，一些四芳基金刚烷八醚在其晶体中包括广泛的不同的客体分子，即使密集的晶体系统对它们是可访问的。在容易与这些主体分子形成溶剂化物的化合物中，有用于有机合成的不稳定底物、试剂和经由气相吸收的BTX芳族化合物。 封装在晶体基质中稳定不稳定的化合物，并将难以结晶的分子置于空间限定的阵列中。 在这里，我们建议更详细地研究封装有机晶体（EnOCs）的现象。 这包括新的四芳基金刚烷的合成和新的封装现象的探索。新的EnOC有可能在捕获，分子存储，分析化学和材料科学领域带来新的应用。

When organic molecules crystallize, they form infinite, ordered three-dimensional lattices of like molecular entities. Occasionally, solvent molecules are included in the crystals, particularly when the crystallizing molecules do not achieve dense packing by themselves. We recently observed that some tetraaryladamantane octaethers include a broad range of different guest molecules in their crystals, even though densely packed crystal systems are accessible to them. Among the compounds that readily form solvates with these host molecules are labile substrates for organic synthesis, reagents and BTX aromatics that are taken up via the gas phase. Encapsulation in the crystalline matrix stabilizes labile compounds and places difficult-to-crystallize molecules in spatially defined arrays. Here we propose to study the phenomenon of encapsulating organic crystals (EnOCs) in more detail. This includes the synthesis of new tetraaryladamantanes and the exploration of new encapsulation phenomena. The new EnOCs have the potential to lead to new applications in the fields of capture, molecular storage, analytical chemistry, and material sciences.
