Abstract
Flavonoids are widely occurring polyphenols of plant origin and well explored in the field of pharmacological activities. Recent studies showed this scaffold to be more dynamic as fluorescent probe. Very rare reports are there in literature on flavones as liquid crystals, for the first time we have synthesized and characterized flavone and bis-flavone derivatives for mesomorphic properties. Compounds 9a–d and 13a–d were studied for liquid crystalline properties by Differential scanning calorimetry (DSC) and Polarizing optical microscopy (POM) studies. The compounds 8, 9a–d, 12, and 13a–d were also studied for antioxidant property by DPPH assay.
