  Closely packed quasi-hexagonal and quasi-tetragonal crystalline phase of
C$_{60}$ molecules (named qHPC$_{60}$) was recently synthesized. Here, we used
DFT simulations to investigate the electronic, optical, and mechanical
properties of qHPC$_{60}$ monolayers. qHPC$_{60}$ has a moderate direct
electronic bandgap, with anisotropic mechanical properties. Their elastic
modulus ranges between 50 and 62 GPa. The results for optical properties
suggest that qHPC$_{60}$ can act as UV collectors for photon energies until 5.5
eV since they present low reflectivity and refractive index greater than one.
The estimated optical bandgap (1.5-1.6 eV) is in very good agreement with the
experimental one (1.6 eV).
