In the perspective of elaborating functional devices based on inorganic molecular materials, it is important not only to continue research on their synthesis and to understand their properties but also to develop new strategies for their processing and shaping. In this context, we show here that centimeter-scale materials exhibiting solid state-like spin-crossover (SCO) properties and easy handling under ambient conditions can be obtained that preserve their thermochromic properties over months. Combining a triazole-based Fe(II) SCO compound with functionalized silica nanoparticles gives rise to nanocomposite soft gels. These gels were used as templates for the formation of a flexible macroporous hybrid silica network via a vapor phase sol–gel process. Further coating with PDMS provided both long-term protection of the material against drying and operationality in aqueous media. Our approach offers new hopes for the development of optical and magnetic devices based on SCO coordination polymers.

包含三唑基Fe（ii）的具有挠性交联特性的柔性聚合物-纳米颗粒杂化材料，用于磁光应用†

从制造基于无机分子材料的功能器件的角度来看，重要的是不仅要继续研究它们的合成并了解其性能，而且还要开发用于其加工和成型的新策略。在这种情况下，我们在这里表明，可以得到展示固态样自旋交联（SCO）特性并在环境条件下易于处理的厘米级材料，这些材料可以在数月内保持其热致变色特性。将基于三唑的Fe（II）SCO化合物与功能化的二氧化硅纳米颗粒结合在一起，可得到纳米复合软凝胶。这些凝胶被用作模板，通过气相溶胶-凝胶法。PDMS的进一步涂层既可长期保护材料免于干燥，又可在水性介质中使用。我们的方法为基于SCO配位聚合物的光学和磁性设备的开发提供了新的希望。
