Abstract: Mesogens are provided based on substituted unsaturated carboxylic acids such as acrylic and methacrylic acid. Substitution of a variety of hydrophobic tails onto the carboxylic acid or acid derivative via the vinyl carbon proximal to the carbonyl of the carboxylic acid results in mesogens that are capable of forming thermotropic and single-phase lyotropic mesophases over a broad range of compositions. The mesophases can be polymerized to lock in the ordered phases.
