The use of spectroscopic techniques, including UV–vis absorption
and fluorescence, combined with quantum chemical calculations, allowed us to
gain a comprehensive understanding of the
(E)-1-(4-hydroxypiperidin-1-yl)-3-(7-methoxybenzo[d][1,3]
dioxol-5-yl)prop-2-en-1-one compounds' photophysical properties. The various
solute and solvent interactions were investigated using Catalan's and Kamlet's
techniques. The compound's excited state dipole moment was estimated using
Lippert, Kawski-Chamma-Viallet, Bakhshiev, and \(E_N^T\) solvent polarity
parameters. It had been found that the excited state dipole moment was greater
than the dipole moment in the ground state. Variations in the solvent's
polarity have a direct impact on the distribution of energy in ES. AS and NAS
showed a surge in Stokes' shift, which rises with increasing solvent polarity.
There could be specific solute-solvent interactions causing this. The redshift
results from an effective intermolecular interface with the ES of the polar
solvents caused by a significant distinction between the solute's ES and the
spreading of GS charge. Further study was conducted to understand further the
compound's molecular properties using computational approaches.
