C60 and C70 electronic absorption spectra in different solvents and matrices.


PMID 21485869

Abstract

The electronic absorption spectra of C60 and C70 molecules have been reported in various solvents viz., polar, aliphatic and aromatic. In addition the electronic absorption spectra of C60 and C70 also recorded in different matrices viz., sol-gel, polymer and thin film. The solvent effect has been observed in polar, aliphatic and aromatic solvents. The aromatic solvent shows larger red shift as compared to other solvents. The solution form electronic absorption spectra C60 and C70 show the conjugation effect and compared with the absorption spectra reported in different matrices like sol-gel, polymer and thin film. In the case of sol-gel, polymer and thin film matrices of C60 and C70, it is found that the broader absorption bands with less intensity suffer from intermolecular interaction.
