Outside Back Cover: Tellurophene‐Induced Triplet–Singlet Spin–Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing (Angew. Chem. Int. Ed. 14/2026)
Abstract
The first multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters incorporating tellurium—the heaviest stable chalcogen—have been developed by Takuma Yasuda and co-workers in the Research Article (e24098). Simply linking a dibenzo[b,d]tellurophene unit dramatically accelerates excitonic spin conversion between triplets and singlets. This design concept is applicable to various MR-TADF and other functional π-conjugated frameworks, enabling advanced optoelectronic applications.
