Abstract
Two new C3 symmetrical star-shaped truxene-based discotic liquid crystals have been designed to study their optoelectronic properties. Both the truxene derivatives exhibited columnar hexagonal self-assembly, confirmed by a thorough analysis using POM, DSC, and XRD. A multilayered OLED device was structured using these mesogens as blue emitters for electroluminescent studies. The best-performing configuration was perceived for devices based on emitter 1b at a dopant concentration of 1 wt% in a well-aligned CBP host, giving a maximum EQE of 2.9%.
