Fulleretic Well-Defined Scaffolds: Donor-Fullerene Alignment Through Metal Coordination and Its Effect on Photophysics.

摘要: Herein, we report the first example of a crystalline metal–donor–fullerene framework, in which control donor–fullerene mutual orientation was achieved through chemical bond formation, particular, by metal coordination. The 13C cross-polarization magic-angle spinning NMR spectroscopy, X-ray diffraction, and time-resolved fluorescence spectroscopy were performed for comprehensive structural analysis energy-transfer (ET) studies fulleretic donor–acceptor scaffold. Furthermore, combination with photoluminescence measurements, theoretical calculations spectral overlap function, Forster radius, excitation energies, band structure employed to elucidate photophysical ET processes prepared material. We envision that well-defined materials could contribute not only basic science fullerene chemistry but would also be used towards effective development organic photovoltaics molecular electronics.
