Thermally Activated Delayed Fluorescence with Narrow Emission Spectrum and Organic Room Temperature Phosphorescence by Controlling Spin-Orbit Coupling and Phosphorescence Lifetime of Metal-Free Organic Molecules

Abstract

This work shows a study of two organic molecules with very similar, large singlet-triplet gap of which one is a TADF emitter and the other an RTP emitter. By investigation of photophysical properties of these compounds, it is possible to explain their distinct behavior. Properties are studied in non-polar polymer and OLED host with further device fabrication. Furthermore, this work presents a CT TADF emitter that shows narrow and resolved electroluminescence (FWHM of 53 nm). The study presents efficient RTP emitter based on the D-D-D structure and also a first acridone-based TADF emitter of D-A-D structure.
