摘要：

By leveraging natural saturated fatty acids with distinct melting points and swift reversible phase transitions, we correlated external thermal cues to monomer and excimer emissions of difluoroboron beta-diketonate fluorophores. This integration yielded a ratiometric fluorescent thermometer showcasing unparalleled sensitivity and thermochromism in the physiological temperature range. Using phase transition materials to control the aggregation state of difluoroboron beta-diketonate fluorophores, a high-sensitivity ratiometric fluorescent thermometer based on monomer and excimer dual emission is achieved.
