synthesized that exhibited strong solution fluorescence and molecular structure and conformation controlled fluorescence photoswitching, solid state fluorescence and halochromism. Hydroxyl substituted molecules (1–4) showed moderate to strong fluorescence in solution depend on solvent polarity and very weak solid state fluorescence. Methoxy substituted molecules (5–7) displayed strong fluorescence both in

Lipert-Mataga correlations. The positive and negative solvatochromism observed from non-polar to polar solvents is also supported using Kamlet-Taft and Catalan multilinear regression analysis. Comparative study of photophysical properties between benzil, phenanthrene and 3,6-diphenylphenanthrene based hydroxyl imidazole derivatives is presented to study the effect of rigidity and extended conjugation.
