Concise Review of TADF: Basic Principles, Material Design, Prospective Applications, and the Role of ROMP in Polymer Synthesis

OLEDs have achieved significant efficiency advancements through the utilization of TADF materials, which leverage RISC to potentially reach up to 100% IQE.TADF materials convert non-emissive triplet excitons into light, addressing the limitations of traditional fluorescent and phosphorescent materials.Although small molecules have predominantly been the focus of TADF research, TADF polymers created via ROMP provide adjustable properties and compatibility with solution-based processing.This review discusses the basic principles of TADF, the design strategies for donoracceptor systems, and the potential applications in various fields, including OLEDs, sensors, bioimaging, and therapeutics.
