| Abstract: | In this paper, the synthesis of thermally activated delayed fluorescence nanoparticles (TADF NPs) is reported using a micelle-confined soft template self-assembly. With vaporing organic solvent in this system, TADF NPs with a diameter of about 500 nm were obtained. The main advantage is to nanoencapsulate these TADF molecules with an amphiphilic polymer. As demonstrated, air-stable nanoparticles with efficient TADF properties are realized in water. The application of these as-prepared TADF NPs as a kind of alternative electrochemiluminescent (ECL) material has also been investigated. The triplet-harvesting ability combined with excellent redox properties endows as-prepared TADF NPs with a high ECL efficiency of 10.82%, which is a marked enhancement over previous results. Therefore, ECL materials with similar behavior to reported TADF materials in this article are desirable in applications such as ECL sensing, imaging, and light-emitting devices.
