This species, [Zn(Salendc)Eu(CH3COO)(DMSO)]·xH2O·0.5CH3CN (x = 3.5–4), has been characterised by XRD, XEDS and SEM and HTEM microscopies. Experimental results suggest the formation of a one-dimensional polymeric compound. The compound behaves as a luminescent material in the solid state. Moreover, it exhibits acidochromic properties upon the addition of a few drops of HCl and in the presence of its vapours. The emission intensity of the bands attributed to the Eu(III) ion can be also modulated by the temperature and by the presence of water, so that this species is a good candidate for its use as a luminescent acid, temperature and water sensor. eng Attribution-NonCommercial-NoDerivatives 4.0 International Reversible acidochromism and thermo-responsive luminescence properties of a novel
