Vibrational properties of new corrole–fullerene dyad and its components

We present first systematic spectral studies of a new corrole–fullerene dyad and its components: modified corrole and suitable spacer. The infrared absorption and Raman scattering spectra were measured in polycrystalline samples, at room temperature. Quantum chemical calculation results were compared with the experimental IR and Raman spectra. An attribution of the strongest IR and Raman bands was proposed. It was found that the strongest excitations in the dyad are mainly related to the excitations of the modified corrole part with some influence from the spacer and fullerene parts.

► New corrole–fullerene dyad has been synthesized.
► The dyad has been characterized using the means of vibrational spectroscopy.
► Infrared absorption and Raman scattering spectra were supported by DFT calculations.
