The development of large pore single-crystalline covalently linked organic frameworks is critical in revealing the detailed structure-property relationship with substrates. One emergent approach is to photo-crosslink hydrogen-bonded molecular crystals. Introducing complementary hydrogen-bonded carboxylic acid building blocks is promising to construct large pore networks, but these molecules often form interpenetrated networks or non-porous solids. Herein, we introduced heteromeric carboxylic acid dimers to construct a non-interpenetrated molecular crystal. Crosslinking this crystal precursor with dithiols afforded a large pore single-crystalline hydrogen-bonded crosslinked organic framework HCOF-101. X-ray diffraction analysis revealed HCOF-101 as an interlayer connected hexagonal network, which possesses flexible linkages and large porous channels to host a hydrazone photoswitch. Multicycle Z/E-isomerization of the hydrazone took place reversibly within HCOF-101, showcasing the potential use of HCOF-101 for optical information storage.

基于杂聚羧酸的单晶交联有机框架
大孔单晶共价连接有机骨架的开发对于揭示与底物的详细结构-性能关系至关重要。一种新兴的方法是光交联氢键分子晶体。引入互补的氢键羧酸构建块有望构建大孔网络，但这些分子通常形成互穿网络或无孔固体。在此，我们引入了杂聚羧酸二聚体来构建非互穿分子晶体。将该晶体前体与二硫醇交联得到大孔单晶氢键交联有机骨架 H C OF-101。X 射线衍射分析显示 H COF-101 作为层间连接的六边形网络，具有灵活的连接和大的多孔通道来承载腙光开关。腙的多循环 Z/E 异构化在 H C OF-101 中可逆地发生，展示了 H C OF-101 用于光学信息存储的潜在用途。
