Fluorochromism
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. WebThe fluorescent excited state for the anion is formed by solvent relaxation around it and conformational relaxation of the molecule itself. Ion-dipole interaction in the ground state is manifested...
