Quantitative Studies of Ground and Excited State Charge Transfer Complexes of Fullerenes with N,N-Dimethylaniline and N,N-Diethylaniline

A comprehensive spectroscopic study of ground state charge transfer complexes and exciplexes of C[sub 60] and C[sub 70] with N,N-diethylaniline (DEA) and N,N-dimethylaniline (DMA) is reported. The pure absorption spectra of ground state complexes and pure exciplex fluorescence spectra of C[sub 60]/C...

Description
Summary:A comprehensive spectroscopic study of ground state charge transfer complexes and exciplexes of C[sub 60] and C[sub 70] with N,N-diethylaniline (DEA) and N,N-dimethylaniline (DMA) is reported. The pure absorption spectra of ground state complexes and pure exciplex fluorescence spectra of C[sub 60]/C[sub 70]-DEA/DMA are determined by use of a chemometrics method principal component analysis - self modeling spectral resolution. The exciplex emissions are strongly solvent dependent. In room-temperature toluene, exciplex emissions are absent and the quenching of monomer fluorescence involves both dynamic and static processes. In room-temperature hexane, the quenching of monomer excited state is dominated by the formation of exciplexes. The observed dual fluorescence for C[sub 60]/C[sub 70]-DEA/DMA in hexane can be explained by a mechanism in which contributions from both prompt and delayed monomer emissions are considered. 36 refs., 12 figs.
