Abstract
ABSTRACT Chirality of optically active liquid crystal molecules has become an important research topic. Different approaches, both theoretical and experimental have been undertaken to create a better understanding of the concept of chirality in liquid crystals. Surprisingly good agreement is found from predictions from single molecules for phase properties. The scaled chiral index with no solvent interaction has been successful in predicting the helical twisting power of a range of dopants in nematic solvents. We present here results for both single molecule studies and molecular dynamics simulations for two biphenyl dopants and discuss the effect of conformational change on the predictions of the scaled chiral index of helical twisting power.
