Photoluminescence and Electro-Optic Kerr Effect in Porphyrin Derivatives of C60
Photoluminescence and electro-optical properties of two C60 fullerene derivatives: with porphyrin (C60-H(2)P) and of an iodide salt of Zn porphyrin (C60-ZnP) (+)I(-) are reported. Both studies were done in solution. In the case of the (C60-H(2)P) the photoluminescence spectra depend strongly on the solvent used and emission from B band is quenched in dioxane. For the idodide salt [C60-ZnP](+)I(-) both emissions from B and Q bands are observed. In all studied cases the photoluminescence at 650 nm is present, however it is excited in the iodide salt only for certain excitation energies. The EO Kerr effect measurements show a very slow rotation of molecules under the applied electric field. This rotation is more complex in the case of the iodide salt.
