A series of new liquid crystalline homopolymers, copolymers, and block copolymers were polymerized from styrene-macroinitiator (SMi) and methacrylates with pendent 4,4′-bis(biphenyl)fluorene (M1) and biphenyl-4-ylfiuorene (M2) groups through atom transfer radical polymerization (ATRP). The number-average molecular weights (Mn) of polymers P1-P4 were 10,007, 14,852, 6,275, and 10,463 g mol-1 with polydispersity indices values of 1.21, 1.15, 1.31, and 1.22, respectively. All polymers exhibit the nematic phase. The thermal, mesogenic, and photoluminescent properties of all polymers were investigated.
