We report several novel thermometers resulting from the temperature-induced aggregation of difluoroboron β-diketonate chromophores. These thermometers exhibit a much wider temperature-dependent fluorescence emission from 445 to 592 nm along with the color change from blue to red in a dilute chloroform solution. Spectroscopy measurements and theoretical calculations confirm that the thermochromic luminescence originates from the reversible change in the noncovalent intermolecular interactions and the abrupt volume shrinkage of the solvent at its melting point. The present work provides a new strategy for rationally designing high-performance thermometers having a wide emission property.

基于二氟硼β-二酮基生色团聚的有机温度计
我们报告了几种新颖的温度计，这些温度计是由温度诱导的二氟硼β-二酮基生色团聚集所致。这些温度计在445至592 nm范围内具有更宽的温度依赖性荧光发射，并且在稀氯仿溶液中颜色从蓝色变为红色。光谱测量和理论计算证实，热变色发光源于非共价分子间相互作用的可逆变化和溶剂在其熔点处的突然体积收缩。本工作为合理设计具有宽发射特性的高性能温度计提供了新的策略。
