| Abstract: | Several oligomers (MWs > 1000 g mol−1) with highly rigid and conjugated aromatic cores, incorporating 1,4-disubstituted phenylene, 2,7-disubstituted fluorene, 1,4-disubstituted thiophene and/or 2,7-disubstituted carbazole rings with lateral and terminal substituents were synthesised as novel organic semiconductors. These novel liquid crystalline oligomers exhibit glass transition temperatures above room temperature, high clearing points and a broad nematic temperature range as well as electroluminescent behaviour in solution-processed devices.
