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. WebCombining meta-triphenylamine or triphenylphosphine with three anthracene fluorophores gives rise to fluorescent non-planar triskelions 1 and 2. The emissive properties of 1 are highly solvatochromic, yielding blue to pale green and even pale yellow fluorescence, whereas the blue emission of 2 is so …
