提高热、化学耐久性和增加比表面积是多孔氢键有机骨架（HOFs）结构和性能改善的两个主要方向。本研究中，一种具有6个羧基的六氮杂苯基（HAT）衍生物通过HAT核与互穿三维网络之间的拟形对接，作为一种合适的构建块，用于系统构建具有高表面积的热耐用和化学耐用的hof。具有羧基联苯基团的HAT衍生物形成稳定的单晶多孔HOF，即使在浓HCl中也具有质子溶剂耐久性，耐热性高达305℃，布鲁诺尔-埃米特-泰勒表面积[SA((BET))]高达1288 m(2) g（-1）。该HOF单晶具有各向异性荧光，可应用于基于坚固功能多孔材料的极化发射体。
Enhancing thermal and chemical durability and increasing surface area are two main directions for the construction and improvement of the performance of porous hydrogen-bonded organic frameworks (HOFs). Herein, a hexaazatriphenylene (HAT) derivative that possesses six carboxyaryl groups serves as a suitable building block for the systematic construction of thermally and chemically durable HOFs with high surface area through shape-fitted docking between the HAT cores and interpenetrated three-dimensional network. A HAT derivative with carboxybiphenyl groups forms a stable single-crystalline porous HOF that displays protic solvent durability, even in concentrated HCl, heat resistance up to 305 degrees C, and a high Brunauer-Emmett-Teller surface area [SA((BET))] of 1288 m(2) g(-1). A single crystal of this HOF displays anisotropic fluorescence, which suggests that it would be applicable to polarized emitters based on robust functional porous materials.
