TADF OLED emitters or Thermally Activated Delayed Fluorescence is a relatively new class of OLED emitter materials that promise efficient and long-lifetime performance without any heavy metals. TADF will facilitate Micro Small. Herein two wide band-gap thermally activated delayed fluorescence TADF host materials based on diphenylsulfone derivatives were developed by rationally tuning the TADF characteristic and charge transport ability through electron-donor engineering. TADF has therefore attracted widespread interest in the OLED community and research into TADF and OLEDS is a popular application of our FS5 and FL1000 photoluminescence spectrometers. Hyperfluorescence TM combines TADF and fluorescence emitters to enable highly efficient emission 100 IQE low. In fact TADF emitters can deliver device efficiencies which can be up to three times higher than for OLEDs based on fluorescent dopants.

Thermally activated delayed fluorescent TADF materials as the third generation of organic electroluminescent materials have many advantages over other organic light-emitting diodes OLEDs materials such as 100 internal quantum efficiency no doping of heavy metals and avoiding the shortages of ordinary fluorescent materials and phosphorescent materials.

An alternative to the use of rare elements like Ir to achieve high EL efficiency involves the use of emitters that harvest S 1 and T 1 excitons via thermally assisted delayed fluorescence TADF. In this report we introduce the routes for efficient radiative decay from S 1 and T 1 states and describe the TADF process in some depth. TADF OLED emitters or Thermally Activated Delayed Fluorescence is a relatively new class of OLED emitter materials that promise efficient and long-lifetime performance without any heavy metals. Emitters showing thermally activated delayed fluorescence TADF in electroluminescent devices rely on efficient reverse intersystem crossing rISC arising from small thermal activation barriers between the lowest excited triplet and singlet manifolds. Materializing the future of OLEDs. TADF has therefore attracted widespread interest in the OLED community and research into TADF and OLEDS is a popular application of our FS5 and FL1000 photoluminescence spectrometers.

Current research on thermally activated fluorescence TADF emitters is mainly based on the molecular levels while the aggregation states of TADF emitters are to be explored deeply. ConspectusSince the seminal work of Tang and Vanslyke in 1987 on small-molecule emitters and that of Friend and co-workers in 1990 on conjugated-polymer emitters organic light-emitting diodes OLEDs have attracted much attention from academia as well as industry as the OLED market is estimated to reach the 30 billion mark by the end of 2018. The TADF mechanism represents a unique photophysical process originated from a series of molecules containing electron donor D and electron acceptor A units or that result from the intermolecular interaction of D and A molecules in the case of exciplexes which allows the up conversion of low energy triplet states usually non emissive at room temperature into high energy and strongly.
