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 BN2Br can be used as a luminescent thermometer and exhibits a high temperature sensitivity (3.67% K^-1), 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.

基于 N,C-螯合四配位有机硼化合物的高灵敏度固体比率发光温度计。

使用单组分有机固态发光体实现比率温度计很有吸引力，但也很有挑战性。在此，我们合成了一系列 N、C-螯合四配位有机硼化合物，并对其结构进行了表征。其中，样品 BN2Br 可用作发光温度计，并表现出较高的温度灵敏度（3.67% K-1）、120-280 K 的较宽响应范围和良好的可逆性，这主要归功于固态下与温度相关的分子间堆叠效应。所提出的比率测温协议可为开发光子温度计提供新的启示。
