Charge transfer in fullerene – porphyrin-derived dyads studied with light-induced electron spin resonance

Study of the contact charge transfer behavior between cryptophanes (A and E) and fullerene by absorption, fluorescence and 1H NMR spectroscopy

“…These unique physical and chemical properties make C 60 a promising candidate for investigating its electron transfer processes with electron-donor compounds [9][10][11][12][13][14]. So far many CT complexes have been found between fullerenes and electron donors including cyclotriveratrylene (CTV), crown ethers, pyrrolidine derivatives and amine derivatives [15][16][17][18].…”

A photo-responsive molecular wire composed of a porphyrin polymer and a fullerene derivative

“…16 Due to this low reorganization energy and also the appropriate energy difference, photoinduced charge-separated states of porphyrin/fullerene assemblies have long lifetimes, and high quantum yields. [17][18][19][20][21][22][23][24][25] On account of these properties, porphyrin wires decorated with fullerene derivatives may work as efficient photo-switchable molecular wires, with higher conductivity during irradiation than in the dark (Fig. 1).…”
