利用固态合成的有机分子构建了一个基于罕见mok拓扑结构的三维氢键网络。该分子是使用超分子保护基团的策略，适用于固态[2+2]光二聚。光二聚提供了一种新的头对头环丁烷产品。环丁烷具有四面体布置的顺式氢键供体（酚）和顺式氢键受体（吡啶基）基团。该产品在固态自组装，形成一个mok网络，表现出双重相互渗透。环丁烷采用不同的构象，以提供氢键供体和受体位点的组合，以符合MOK网的结构要求。
A three-dimensional hydrogen-bonded network based on a rare mok topology has been constructed using an organic molecule synthesized in the solid state. The molecule is obtained using a supramolecular protecting-group strategy that is applied to a solid-state [2+2] photodimerization. The photodimerization affords a novel head-to-head cyclobutane product. The cyclobutane possesses tetrahedrally disposed cis-hydrogen-bond donor (phenolic) and cis-hydrogen-bond acceptor (pyridyl) groups. The product self-assembles in the solid state to form a mok network that exhibits twofold interpenetration. The cyclobutane adopts different conformations to provide combinations of hydrogen-bond donor and acceptor sites to conform to the structural requirements of the mok net.
