| Outline of Annual Research Achievements |
Successful fabrication of a novel molecularly-thin nitrogen-doped 2D fullerphene by the carbonization of assembled fullerene C60-ethylenediamine (EDA) thin film, which exhibits a hierarchically micro/mesoporous structure at its surfaces. N-doping of fullerphene is dominated by pyrrolic and quaternary nitrogen
atoms, which allow selective and repetitive adsorption and desorption of lowmolecular-weight carboxylic acid vapors through noncovalent interactions.
Furthermore, novel micron-sized two-dimensional self-assembled fullerene rosettes and rice-husk shaped fullerene crystals with micropore architecture showed high sensitivity to aliphatic acid vapors compared to the aromatic vapors.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The Covid-19 situation has improved and we could work in the lab smoothly.
|
| Strategy for Future Research Activity |
Fabrication of morphology-controlled hierarchical micro/mesoporous fullerene crystals with high surface area and well-developed porosity and composite with metallic nanoparticles and their oxide to enhance the selectivity and sensitivity to the targeted vapors such as formaldehyde, toluene, and acid vapors.
