Solvatochromism Of NNDAP-O-CH3

The solvatochromic properties of a novel fluorophore, 4-[2-[2-(dimethylamino)-3-pyridyl]ethynyl]anisole (NNDAP-O-CH3), developed by Dr. Tanay Kesharwani of The University of West Florida was studied. The absorption and emission spectra of the fluorophore in various solvents were measured. The ground state and singlet excited state dipole moments were determined using the Bilot-Kawski, Lippert-Mataga, Bakhshiev, and Reichardt correlation methods. The magnitude to which a certain solvent property contributes to the observed solvatochromic shifts was investigated using both Kamlet-Taft and Catalan models. The experimental system and environment are being computationally modeled in Gaussian16. Predictions of the software will be compared to experimental evidence to propose structural and dynamic factors contributing to the phenomenon as well as to predict other properties of the molecule.
