摘要: The structure of nematic liquid crystals formed by bent-core mesogens (BCMs) is studied in the context Monte Carlo simulations a simple molecular model that captures symmetry, shape, and flexibility achiral BCMs. results indicate formation (i) clusters exhibiting local smectic order, orthogonal or tilted, with strong in-layer polar correlations antiferroelectric juxtaposition successive layers (ii) large homochiral domains through helical arrangement tilted clusters, while produce (untwisted) states.
