Py-COF is a recently emerged porous organic framework material with unique adsorption properties. It is synthesized using self-condensation building blocks with formyl and amino groups, and its theoretical pore size is 1.38 nm. Therefore, a metallofullerene Sc3C2@C80 unit (with a size of approximately 0.8 nm) can enter a nanoscale pore of Py-COF.

Researcher Wang from the Institute of Chemistry, Academy of Sciences, has developed a nano spin sensor based on metallofullerene for detecting gas adsorption inside porous organic frameworks. Paramagnetic metallofullerene, Sc3C2@C80, is embedded in nanoscale pores of a pyrene-based covalent organic framework (Py-COF). The EPR Spectroscopy (CIQTEK EPR200-Plus) is used to record the EPR signals of the embedded Sc3C2@C80 spin probe for N2, CO, CH4, CO2, C3H6, and C3H8 adsorbed within Py-COF. The study reveals that the EPR signals of embedded Sc3C2@C80 exhibit a regular dependence on the gas adsorption performance of Py-COF. The research findings are published in Nature Communications under the title "Embedded nano spin sensor for in situ probing of gas adsorption inside porous organic frameworks. "
