Annotation: Organic light-emitting diodes offer a number of advantages. They can be used to produce thin and flexible displays with a brighter and richer colour gamut compared to competing devices. Organic light-emitting diode technology is one of the leading technologies, particularly in the manufacturing of smartphones, TVs and lighting devices. Efficient organic light-emitting diodes employ a variety of organic semiconductors in their emissive layers. Proper selection of such materials, ensuring compatibility between the energy levels of the host and the emitter, enables the efficient electricity-to-light conversion. One of the many advantages of organic semiconductors is the ability to easily modify their molecular structure by changing various fragments that affect their semiconducting properties. In this work, several series of emitters and hosts were synthesized and studied, detailing their synthesis, characterization and performance in prototype devices with external quantum efficiency reaching up to 30%.
