在乙腈、硝基苯和四氢呋喃中，分别从苯甲腈基卟啉有机连接体4，4 ′，4 ″，4 ′-（卟啉-5，10，15，20-四基）四苯甲腈（PTTBN）中合成了3个氢键有机骨架（霍夫-26，霍夫-27，霍夫-28），并对其结构进行了表征.仔细检查的HOFs的晶体结构表明，PTTBN单元形成一个二维氢键SQL网络，但不同的氢键连接性，包装模式，和主客体相互作用。这些HOFs中的孔系统可以被客体分子系统地调制，并从离散的空腔调谐到具有不同尺寸的一维通道。通过能量分解分析，研究了膜层间和层内相互作用能对溶剂依赖性自组装的影响。
Three hydrogen-bonded organic frameworks (HOFs) (HOF-26,HOF-27,HOF-28) have been crystallized from a benzonitrile-based porphyrinic organic linker 4,4′,4″,4‴-(porphyrin-5,10,15,20-tetrayl)tetrabenzonitrile (PTTBN), in ethylbenzene, nitrobenzene, and tetrahydrofuran, respectively, and structurally characterized. Close inspection of the crystal structure of the HOFs reveals that PTTBN units form a two-dimensional hydrogen-bonded sql network but with varied hydrogen bonding connectivities, packing patterns, and host–guest interactions. The pore system in these HOFs can be systematically modulated by the guest molecules and tuned from discrete cavities to one-dimensional channels with distinct dimensions. Energy decomposition analysis was carried out to investigate the intralayer and interlayer interaction energy to understand the solvent-dependent self-assembly.
