Supramolecular coordination complexes (SCCs) are popular for their structural diversity and functional adaptability, which make them suitable for a wide range of applications. Photophysical and mechanical performance of SCCs are the most attractive characteristics, yet their ionically conductive behavior and potential in electrical sensing have been rarely investigated. This study reports a well-designed SCC that integrates orthogonal metal coordination and host–guest interactions to achieve sensitive electrical thermal sensing. Owing to the thermodynamic nature of the host–guest interaction, the SCC encounters thermally induced disassembly, leading to significantly enhanced ion mobility and thus allowing for the precise detection of minor temperature variation. The SCC-based thermometer is then fabricated with the assistance of 3D printing and demonstrates good accuracy and reliability in monitoring human skin temperature and real-time temperature changes of mouse during the whole anesthesia and recovery process. Our findings provide an innovative strategy for developing electrical thermometers and expand the current application scope of SCCs in electrical sensing.

正交金属配位和主客体相互作用形成的热敏超分子配位络合物，用于电子温度计


超分子配位配合物（SCC）因其结构多样性和功能适应性而广受欢迎，这使得它们适用于广泛的应用。 SCC 的光物理和机械性能是最具吸引力的特性，但其离子导电行为和在电传感方面的潜力却很少被研究。这项研究报告了一种精心设计的 SCC，它集成了正交金属配位和主客体相互作用，以实现灵敏的电热传感。由于主客体相互作用的热力学性质，SCC 会遇到热诱导分解，导致离子迁移率显着增强，从而可以精确检测微小的温度变化。然后借助3D打印制作基于SCC的温度计，在整个麻醉和苏醒过程中监测人体皮肤温度和小鼠实时温度变化方面表现出良好的准确性和可靠性。我们的研究结果为开发电子温度计提供了创新策略，并扩大了 SCC 目前在电传感领域的应用范围。
