| Outline of Research at the Start |
QCM sensing performance of the hierarchical nanoporous fullerene crystal-based sensors contribute greatly to the sensing response due to its unique pi-conjugated structure, high hydrophobicity and strong van der Waals and pi-pi interactions, which is not possible with conventional materials.

| Outline of Final Research Achievements |
We have successfully fabricated novel corn-husk-shaped fullerene C60 crystals (CHFCs), molecularly thin nitrogen-doped 2D fullerphene and fullerene rosettes through the liquid-liquid interfacial precipitation method. Due to the hierarchically porous structures and high surface area and nitrogen doping these materials showed excellent quartz crystal microbalance (QCM) sensing results. The CHFCs sensitive to acetic acid vapors. While fullerphene is sensitive to formic acid over acetic acid in the vapor. Fullerene rosettes are selective to acids against basic guests (formic acid/pyridine > 30) or aromatic guests (formic acid/toluene > 110), the fullerene rosette based QCM sensor also showed superior performances. Our results show ultrathin two-dimensional (2D) nanoporous materials offer enhanced sensitivity and high spatial resolution in sensing applications making them important for the selective discrimination of guest molecules.
