Magnetic Switching of Thermally Activated Delayed Fluorescence for Organic Lighting and Lasing

Abstract

Thermally activated delayed fluorescent (TADF) is a recently discovered phenomena which has the potential to be a game changer in electroluminescent materials. Conventional organic electroluminescent molecules are limited to a maximum of 25% internal quantum efficiencies due to the population of singlet states in the molecule. TADF describes a method to increase this by inducing thermally activated reverse intersystem crossing from triplet to singlet states. In this proposal we plan to investigate new methods make this process more efficient. Our approach involves the use of magnetic field to access the spin-orbit coupling in the excited molecule and use it as a means of controlling the TADF phenomenon. To this end we plan to conduct fundamental as well as exploratory research.
