Dendritic mesogens—dendrimers that form mesophases—are the third group of liquid crystalline polymers (LCPs), following main-chain and side-chain LCPs. The synthesis of a series of different generations of dendromesogens (see Figure) is reported and their thermal behavior, molecular shape, and the textures observed by polarizing microscopy described. The role of hydrogen bonds in the formation of such mesophases is discussed.
