With HOF-FJU-1, an easy-synthesized, recyclable, and highly stable ultramicroporous hydrogen-bonded organic framework, as its main object, the research shows that this material possesses a suitable pore environment and complementary electrostatic potential distribution fitting well to C₂H₂, thus showing extra strong affinity to it, and further improving the selectivity of specific gases in gas mixture (as illustrated in following figure).

The research results, entitled “An Ultramicroporous Hydrogen-Bonded Organic Framework Exhibiting High C₂H₂/CO₂ Separation”, were published in the top international chemistry journal, Angew.Chem.Int.Ed., and rated as Very Important Paper.

FNU is the first organization of the paper, with Yang Yisi, the doctoral candidate of the class of 2019 in the College of Chemistry and Material Science of FNU, as the first author, and Professor Zhang Zhangjing as the corresponding author. This research was supported by the National Natural Science Foundation of China and the Natural Science Foundation of Fujian Province.
