The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters

Advanced Functional Materials, EarlyView.
A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different

Exploring BINOL-O-BODIPY-Based Dimers as Advanced Chromophoric Platforms Enabling Triplet State Population

Chemistry Proceedings, 2022
An example of a new BODIPY design with triplet state population is reported: BINOL-O-BODIPY-based dimer. This new design combines two easily accessible structural features with a demonstrated capability of populating triplet states without the need for ...
