which was characterized by 1H and 13C NMR spectroscopy, mass spectrometry, and elemental analysis. A thermally stable HOF-1 from macrocycle 1 was crystallized from hexane–THF, and its porous property was studied. The crystallographic analysis revealed that the void space was maintained by the π–π, H-bond, and C–H−π interactions between the aromatic moieties in a solid state. The framework changes while
的反应叔丁基3,5-二氨基与氰尿酰氯,得到的三嗪类的大环1在44.3%的产率,其特点是1 H和13 C NMR谱,质谱和元素分析。将大环1的热稳定HOF-1从己烷-THF中结晶,并研究了其多孔性。晶体学分析表明,空隙空间由固态芳族部分之间的π–π,H键和C–H–π相互作用保持。框架在失去溶剂的同时会发生变化,并且在辐照时会产生各种发射强度。完全除去溶剂后,HOF 1的空隙空间 仍可用于溶剂化,令人惊讶的是,根据粉末XRD研究,骨架在吸附溶剂后几乎恢复了。
