The development of organic solids for applications in materials science requires a fundamental understanding of how close packing of molecules can affect structure and function. We report here nonporous organic crystals that release entrapped guest molecules upon application of UV light. We show components of binary cocrystal solvates to undergo an intermolecular photoreaction to generate ternary cocrystals that results in release of entrapped solvent molecules. The phototriggered guest release occurs in a single-crystal-to-single-crystal transformation that is in the absence pores and channels in the solid. The cocrystals are composed of a tetratopic hydrogen-bond-acceptor molecule synthesized in the solid state. The UV-light results in [2 + 2] photodimerization of an isocoumarin to generate a ternary cocrystal with cyclobutane molecules that support guest release.

无孔有机晶体的光触发客体释放：二元共晶溶剂化物到三元共晶的显着单晶到单晶转化

用于材料科学应用的有机固体的开发需要对分子的紧密堆积如何影响结构和功能有基本的了解。我们在此报告无孔有机晶体，在应用紫外线后释放捕获的客体分子。我们展示了二元共晶溶剂化物的成分进行分子间光反应以产生三元共晶，从而导致被捕获的溶剂分子的释放。光触发客体释放发生在单晶到单晶的转变中，即固体中没有孔和通道。共晶由固态合成的四位氢键受体分子组成。
