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.
