Solution-processable phenothiazine and phenoxazine substituted fluorene cored nanotextured hole transporting materials for achieving high-efficiency OLEDs

In this work, a novel series of phenothiazine and phenoxazine substituted fluorene core-based solution-processable nanotextured HTMs was reported. Of these, the phenoxazine material showed a superior performance in phosphorescent yellow and TADF green OLEDs.
