Abstract

We have synthesised nine monomeric azaheterofullerene (AZA) derivatives, RCN, with a wide variety of different side chains R and investigated their spectroscopic and photophysical properties in toluene and o-dichlorobenzene (ODCB). Measurements include their ground-state absorption spectra, molar absorption coefficient (ε), fluorescence spectra, fluorescence quantum yields (Φ), singlet-state lifetimes (τ), triplet-state absorption spectra, triplet molar absorption coefficients (ε), singlet oxygen (Φ), and triplet state (Φ) quantum yields. The replacement of a carbon by a nitrogen atom in the C sphere strongly affects most of the spectroscopic and photophysical properties. The chemical nature of the R moiety has definite effects on these properties in contrast with minor effects on the chemical nature of the addends in [6,6]-ring bridged monoadduct methano[60]fullerene derivatives. These effects concern properties of the ground state, singlet excited state, and triplet states of our nine RCN derivatives and in particular the values of photophysical parameters ε ε, Φ, and Φ, which are significantly lower than those of analogous monoadduct [6,6]-ring bridged methano[60]fullerene derivatives. © 2006 Wiley-VCH Verlag GmbH & Co.
