By means of a TDDFT dynamics simulation, we have clarified that a molecular heterojunction of aπ一conjugated dendrimer, composed of oligo-phenylenevinylene antenna and Zn-phthalocyanine core, and a C_60 molecule exhibits light-harvesting charge separation behavior. We have also studied the relationship between geometrical and electronic structures of 1D peanut-shaped fullerene polymers, shown the spontaneous encapsulation of linear molecules into carbon nanotubes, and performed simulations of chemical reactions and calculations of photoabsorption spectra.
