A molecular dual-center emitter for ratiometric optical thermometry
Abstract
energy transfer mediated by the bridging Schiff base ligand, accounting for the temperature-dependent dual emission. Moreover, ZnSm can be readily processed into a transparent and flexible poly(methyl methacrylate) (PMMA) film (ZnSm@PMMA) while retaining its ratiometric thermometric performance, thus greatly enhancing its applicability for practical thermal mapping and device-integrated sensing. This work presents a robust molecular design strategy for developing high-performance, dual-center emissive ratiometric optical thermometers. Furthermore, the readily distinguishable color change in the visible range for both ZnSm and its film highlights their potential for advanced optical anti-counterfeiting and information encryption applications.
