Control temperature fluctuations with replaceable spin-crossover material
a) Schematic of the behavior of SCO materials during the day-night cycle. b) Schematic of work of SCO material under solar radiation. When the weather is hot, and the material is in the HS (white) state, light is reflected and the increase in room temperature is controlled. In contrast, under cold temperatures, the material exhibits the LS state (pink), so more wavelengths are absorbed and the room gets hotter. c) Illustration of rotational transition under external stimuli.

DOI: 10.1002/advs.202202253 Reducing the heat island effect through thermal regulation mechanisms on building elements can improve human thermal comfort and the living environment in urban areas. Passive thermal control systems that combine with roofs, windows or walls, and operate without the need for electricity, are an energy efficient and environmentally friendly solution. Phase change materials minimize temperature fluctu
