Crossing a barrier: Molecules with saturated ER2 units (E=C or Si, R=electron‐releasing group) inserted between two π‐conjugated segments have electronic and optical properties that resemble those of cross‐conjugated molecules (see figure). This cross‐hyperconjugation provides a deeper understanding of the conjugation phenomenon, and is an alternative to cross‐conjugation in the design of molecules for nano and materials applications.
Durchlässige Grenze: Moleküle, in denen gesättigte ER2‐Einheiten (E=C oder Si, R=elektronenschiebende Gruppe) zwischen zwei konjugierten π‐Systemen eingeschoben sind, zeigen ähnliche elektronische und optische Eigenschaften wie kreuzkonjugierte Moleküle (siehe Bild). Diese Kreuz‐Hyperkonjugation bildet eine Alternative zur Kreuzkonjugation beim Entwurf von Molekülen für Nanostrukturen und Materialien.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
