Choline-geranate (CAGE) ionic liquids are emerging as powerful topical delivery media, yet their impact on the photochemistry of metal-based phototherapeutics remains unexplored. Here we show that CAGE ILs can substantially reshape the excited-state landscape of Ru polypyridyl complexes, promoting ligand photorelease in a prototypical PDT scaffold while preserving the expected behaviour of photo-labile and photo-inert analogues.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
