Abstract

The thermochromic behaviour of spin crossover complexes is desirable for noninvasive thermometry technologies. In this work, we have developed an easy-to-use flexible temperature sensor based on color change accompanying the spin state switching. The sensor consists of an SCO complex, {Fe(Quin)2[Pt(CN)4]} (Quin = quinazoline), embedded in a transparent PDMS substrate using the mould casting method. The decomposition of the colors into individual RGB channels using image analysis provides a straightforward and accurate method for estimating temperature. The qualitative performance trials of the sensor demonstrate its versatility across various applications, including (a) heat transfer monitoring, (b) temperature mapping, and (c) hotspot detection. These trials establish the sensor's ability to operate effectively in a wide range of real-life scenarios.

自旋交叉驱动的热致变色温度传感器,用于通过图像分析监测传热†
自旋交叉配合物的热致变色行为是非侵入式测温技术所需要的。在这项工作中,我们开发了一种易于使用的柔性温度传感器,该传感器基于伴随自旋状态切换的颜色变化。该传感器由SCO配合物{Fe(Quin)2[Pt(CN)4]} (Quin =喹唑啉)组成,采用模铸法嵌入透明PDMS衬底中。使用图像分析将颜色分解为单独的RGB通道,为估计温度提供了一种简单而准确的方法。该传感器的定性性能试验证明了其在各种应用中的多功能性,包括(a)传热监测,(b)温度测绘和(c)热点检测。这些试验确定了传感器在广泛的现实生活场景中有效运行的能力。
