▎ 摘　　要

Past decades we have witnessed many breakthroughs in research on liquid crystals (LCs) as well as significant amplification in the application of LCs. LCs are currently attracting great attention of scientists from all over the world where various researches have been implemented on the varied facets of LCs. In this review we present some recent developments in the field of discotic liquid crystals (DLCs). A large number of DLCs from various aromatic cores have been realised. However, due to paucity of space only DLCs derived from four main aromatic cores, benzene, triphenylene, hexabenzocoronene and graphene, are covered here. An outlook on these emerging two-dimensional organic semiconductor materials with relevant scientific application background has been presented. [GRAPHICS]
