dc.description.abstractWe report temperature dependent measurements of birefringence (Delta n), splay (K(11)), bend (K(33)) elastic constants and rotational viscosity (gamma(1)) of mixtures of rod-like and bent-core molecules. K(11) and Delta n remain almost constant for all the mixtures whereas K(33) is always lower than K(11) and further decreases with increasing concentration of bent-core molecules in the mixtures. Apart from the large jump in Delta n at the nematic-isotropic transition (NI) a significant jump in Delta n at the nematic-smectic transition (NS) is also observed that increases with increasing mol% of the bent-core compound in the mixtures. Rotational viscosity increases by a factor of four when the concentration of the bent-core compound increased from 0 to 10 mol%. The results are discussed on the basis of their structural similarity and mutual alignment in the nematic phase.en
