Abstract
:
A novel solvatochromic ferrocenyl methine dyes has been synthesized by condensation of ferrocen-3-caboxaldehyde with active methylene compounds under Knoevengel conditions and characterized by UV-vis in a range of solvents. Compound 1a has a red shift in ?-?* and a blue shift increases with solvent polarity in the MLCT (M?A) while 1b-1d variation of red as well as blue shifts from both states. No d-d transition is observed in these compounds. These shifts are interpreted by different dipole moments in the ground and excited state as well as solvent interaction between solute/solvent and H-bonding with the acceptor.
