Weit weniger n‐Polymermaterialien (mit niedrigem LUMO und HOMO; Elektronenakzeptoren) als p‐Polymermaterialien (mit hohem LUMO und HOMO; Elektronendonoren) sind bekannt. In ihrer Zuschrift auf S. 3719 ff. wandeln J. Liu und Mitarbeiter konjugierte Polymere von Elektronendonoren in Elektronenakzeptoren um. Ihre Strategie umfasst den Austausch einer C‐C‐ gegen eine B←N‐Einheit und senkt sowohl das LUMO...
The key parameters of conjugated polymers are lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) energy levels. Few approaches can simultaneously lower LUMO and HOMO energy levels of conjugated polymers to a large extent (>0.5 eV). Disclosed herein is a novel strategy to decrease both LUMO and HOMO energy levels of conjugated polymers by about 0.6 eV through...
