5,11‐Di(thiophen‐2‐yl)Tetracene: A Novel Tetracene Derivative for Efficient Singlet Fission with Enhanced Physical and Chemical Stability in Thin Films (Adv. Funct. Mater. 42/2025)

Vapor Deposited Thin Films In their Research Article (10.1002/adfm.202423223), Jeong-Il Park, Dongho Kim, Woojae Kim, and co-workers report a new dithienyl-substituted tetracene derivative that exhibits remarkably enhanced physical and chemical stability in thin films, along with a near-unity yield of triplet pair formation. This study underscores the significance of subtle molecular engineering in thin-film fabrication, demonstrating how minor structural modifications can greatly expand the practical applicability of organic semiconductors.
