Synthesis, Electronic Properties and OLED Devices of Chromophores Based on $\lambda ^5$‐Phosphinines

Abstract : A new series of 2,4,6-triaryl-λ -phosphinines have been synthesized that contain different substituents both on the carbon backbone and the phosphorus atom of the six-membered heterocycle. Their optical and redox properties were studied in detail, supported by in-depth theoretical calculations. The modularity of the synthetic strategy allowed the establishment of structure-property relationships for this class of compounds and an OLED based on a blue phosphinine emitter could be developed for the first time.
