This article describes efforts toward the development of a new core for calamitic mesogens based upon the introduction of an extended heteroaromatic boron-containing ring. A series of tri-catenar mesogenic boronate ester derivatives of the 2-phenyl-1, 3, 2-benzodioxaborole has been synthesized and characterized. The flat central core appeared to be a suitable feature for these derivatives to support anisotropic alignment. Additionally, these ...
