This paper presents the results of UV/vis, fluorescence, FT-IR, DOSY, and DFT study of a novel non-covalent supra molecular systems based on zinc(II) bis(dipyrromethenate)s ([Zn2L2]) with C-60. It was found that zinc(II) bis (dipyrromethenate) forms stable supramolecular pi-pi-complexes ([Zn2L2(C-60)(4)]) with C-60. DFT calculations revealed stable complexation between [Zn2L2] and C-60. The [Zn2L2(C-60)(4)] LUMO energy levels are predominantly spread on the C-60 unit and the HOMO energy levels are mainly spread on the [Zn2L2]. The photoinduced electron transfer testing by the substantial fluorescence quenching of the [Zn2L2] by non-covalent bonded C-60 gives the positive result that shows prospects of the studying [Zn2L2(C-60)(4)] as the active layers in solar energy conversion devices.
