Abstract
The effect of solvent on the absorption and fluorescence spectra of two liquidcrystalline molecules LC1 and LC2 were studied. These data were used to evaluatethe values of the change in the dipole moment between the ground and excitedstate and the first-order hyperpolarizability “β” in each solvent. The values of βgives an indication of how these liquid crystalline samples can find applicationsas nonlinear materials. The β values are in the range 1–1.9 × 1029 esu for LC1and LC2. The values of β indicate that these compounds can be used as goodnonlinear materials. Here solvatochromism has been used as an effective tool toestimate the hyperpolarizability in solution.
