A state-switchable TADF macrocycle for multi-analyte sensing and hydrogen gas-driven emission enhancement

Raktim Deka; Dinesh Singh; Manjeet Singh et al.

Communications Chemistry, Vol. 9 No. 1 · 2026 · English · DOAJ Scopus

Abstract Photochemical sensing demands systems that adjust their optical properties without altering chromophore structure. Here, we report CPCQ, a thermally activated delayed fluorescence (TADF)-active macrocycle, as a responsive platform for optical sensing. CPCQ shows a photoluminescence quantum…
