AI Article Synopsis
- Researchers developed a series of specific organoboron compounds aimed at improving ratiometric thermometers using single-component organic materials.
- One of the compounds showed promising results as a luminescent thermometer, boasting a high temperature sensitivity of 3.67% per Kelvin and functioning effectively within a wide temperature range of 120-280 Kelvin.
- The effectiveness of this thermometer is attributed to temperature-induced changes in how the molecules stack together, providing a novel approach to designing photonic thermometers.
Article Abstract
Realizing ratiometric thermometers using single-component organic solid-state luminophores is attractive but challenging. Here, we synthesized a series of N,C-chelated tetra-coordinated organoboron compounds and characterized their structures. Among them, sample can be used as a luminescent thermometer and exhibits a high temperature sensitivity (3.67% K), a wide response range of 120-280 K, and good reversibility, which is mainly due to the temperature-dependent intermolecular stacking effect in the solid state. The proposed ratiometric thermometry protocol may provide new insights for developing photonic thermometers.
