Photochromic Benzo[]phosphole Oxide with Excellent Thermal Irreversibility and Fatigue Resistance in the Thin Film Solid State Direct Attachment of Dithienyl Units to the Weakly Aromatic Heterocycle
Overview
Affiliations
A novel photochromic benzo[]phosphole oxide has been demonstrated to display photochromic properties with excellent fatigue resistance and thermal irreversibility in polymethylmethacrylate (PMMA) thin film under ambient conditions. The remarkable photochromic behaviour can be achieved by rational molecular design, in which the weakly aromatic phosphole oxide is directly incorporated into the photo-responsive dithienylethene units. Photopatterning photoinduced colouration and decolouration has been performed to demonstrate the repeatable and distinct transformation between the bistable states, making it a promising candidate with photoswitching properties for optoelectronic applications.
