چکیده انگلیسی
A detailed investigation of the absorption and emission characteristics of bichromphoric compounds: 9-phenyl-9-fluorenol and 2-dimethylamino-9-phenyl(4â²-dimethylamino)-9-fluorenol was carried out in non-polar and polar solvents at different temperature. The spectral data were used to obtain the outer-sphere solvent reorganization energy, λouter, and the intramolecular reorganization energies: λi* (associated with the vibrations for which hνkT). They were compared with the destabilization energy Edest. The results of steady-state and kinetic investigations as well as the data of quantum chemical calculation confirm the presence of the two α and β different conformers in the ground and excited state for studied molecules.
