Two-colour photoswitching in photoresponsive inorganic thin films
Artikel i vetenskaplig tidskrift, 2021

Herein we report the first example of an inorganic photochromic material that allows for spatial addressability. We designed a photoresponsive thin film based on a ruthenium sulfoxide complex, [Ru(deeb)2PySO-iPr]2+, which was immobilized onto a mesoporous ZrO2 surface. The resulting material allows for all-optical detection and shows reversible, selective, photochromic behavior that can be cycled back and forth. The photosiomerization quantum yield is lower on the film than in solution which is attributed to a combination of the immobilization and steric hindrance by molecules in close proximity as evident from a surface coverage dependence of the photoisomerization quantum yield. The results reported here provide an important step towards inorganic photoswitchable materials.
