Bistabiles Schalten der π‐Konjugation in einem Dithienylethen‐verbrückten lumineszierenden Trityl‐Diradicaloid

open access: yesAngewandte Chemie, EarlyView.
Photoschalter, die die π‐Konjugation beeinflussen, bieten eine wirkungsvolle Strategie für die externe Manipulation von lumineszierenden Diradikalen. Dithienylethen‐verbrückte persistente Trityl‐diradikaloide, DTE‐TTM2 und F6‐DTE‐TTM2, zeigen ein bistabiles Schalten ihrer optischen, elektrochemischen und magnetischen Eigenschaften.

Bistable Switching of π‐Conjugation in a Dithienylethene‐Bridged Luminescent Trityl Diradicaloid

open access: yesAngewandte Chemie International Edition, EarlyView.
Photoswitches that affect π‐conjugation offer a powerful strategy for external manipulation of luminescent diradicals. Dithienylethene‐linked persistent trityl diradicaloids, DTE‐TTM2 and F6‐DTE‐TTM2, exhibit bistable switching of their optical, electrochemical and magnetic properties.
