title: Cyclic ureas as novel building blocks for bent-core liquid crystals.
abstract: Cyclic ureas represent a new class of bent-core liquid crystals which, depending on the ring size and other structural parameters, can form a series of polar (ferroelectric and antiferroelectric), as well as non-polar, tilted and non-tilted smectic and undulated smectic phases.
