Front Cover: Highly Luminescent Blue Emitter with Balanced Hybridized Locally and Charge‐Transfer Excited‐States Emission (ChemPhotoChem 3/2023)

Abstract

The Front Cover illustrates the structure of a highly blue luminescent emitter lighting up dark space. The electronic structure of this compound reveals emission from a balanced hybridized local and charge‐transfer (HLCT) excited state as shown by multi‐reference quantum chemical calculations. The emitter was implemented by vacuum deposition in an OLED device that exhibits an EQE (external quantum efficiency) of 2%. More information can be found in the Research Article by Thomas J. J. Müller and co‐workers.
