Controlling the Photophysical Properties and Hyperpolarizability Values of Synthesized Indan-1-one Derivatives with Different Position of Bromine Atoms and Molecular Interaction.

Abstract

The polarity of an environment can modify molecular optical characteristics. In this study, the spectroscopy and DFT methods were applied to study environment effects. Multi-parameter models based on polarity factors were used. In addition, spectroscopic data were applied to determine the nonlinear optical properties of Indan-1-one compounds in different environments. The experimental results emphasize the importance of the dipolarity/polarizability parameter in hyperpolarizability of samples in similar behavior to their linear optical behavior. Hence, the studies on the nature of a solvent environment and its effects on the linear responses of Indan-1-one compounds provide an effective way to estimate the dominant solvent polarity effects on the nonlinear hyperpolarizability of the studied molecules. On the other hand, Indan-1-one compounds with their good nonlinear properties can be used in various optical phenomena.
