Fluorescence spectroscopic and time-dependent DFT studies for intramolecular excimer formation of Di-9H-fluoren-9-yldimethylsilane: dynamics and energetics for conformational change.

Intramolecular excimer formation of di-9H-fluoren-9-yldimethylsilane in various solvents was studied by means of steady-state and time-resolved fluorescence spectroscopies. Solvent viscosity effect on the kinetics for the monomer-excimer transition was found to be very slight, indicating that the transformation is accompanied by a slight conformational… CONTINUE READING
