28.4: Invited Paper : Development of Tetradentate Pt Complexes for Efficient, Stable, and High Color Purity Blue OLEDs

In this report we discuss the development of blue OLEDs employing tetradentate platinum complexes. We will discuss the development of a wide range of efficient, blue‐emitting Pt complexes enabling OLEDs with record purity blue emission of (0.15, 0.08), external quantum efficiencies exceeding 25%, or blue OLEDs with operational lifetimes of over 2000h.
