Fluorochromism
WebDec 28, 2024 · Abstract Uni-directional multi-state fluorochromic scaffolds are valuable photofunctional molecules and yet scarce. We report a general approach for their design, … WebThe molecule itself is an AIEgen and shows reversible mechano-fluorochromism after grinding. It was found responsive towards Zn 2+ (LOD = 8.05 × 10 −8 M) and CO 3 2− ions. The sensing mechanism of the molecule with Zn 2+ was ascribed to the inhibition of PET transfer and consequently of the ESIPT mechanism.
