Abstract

Polymer-based composite films represent a promising approach for developing recyclable catalysts. In this study, a [Fe(NH₂trz)₃](NO₃)₂ @TPU composite film with spin crossover properties was fabricated using the blade casting method. Various characterisation techniques confirmed the uniform distribution of [Fe(NH₂trz)₃](NO₃)₂ particles within the TPU matrix, while maintaining the spin-crossover properties of the embedded complex. The composite film exhibited excellent catalytic efficiency and reusability in acetalization reaction, enabling efficient catalysis for up to 11 cycles under batch conditions and sustained activity for 7 hours under flow conditions. In addition, the color of the film served as a convenient visual indicator of its suitability for reuse in subsequent catalytic reactions. This study demonstrates that [Fe(NH₂trz)₃](NO₃)₂ @TPU composite film can serve as an effective and recyclable catalysts for acetalization reactions.

自旋交联复合薄膜作为可回收催化剂用于缩化反应。

聚合物基复合薄膜是开发可回收催化剂的一种很有前途的方法。本研究采用叶片铸造法制备了具有自旋交叉性能的[Fe(NH2trz)3](NO3)2 @TPU复合薄膜。各种表征技术证实了[Fe(NH2trz)3](NO3)2颗粒在TPU基体中的均匀分布，同时保持了嵌入配合物的自旋交叉特性。复合膜在缩醛反应中表现出优异的催化效率和可重复使用性，在间歇条件下可高效催化11次，在流动条件下可持续催化7小时。此外，薄膜的颜色作为一种方便的视觉指标，表明其在随后的催化反应中是否适合重复使用。研究表明，[Fe(NH2trz)3](NO3)2 @TPU复合膜可作为一种有效的、可回收的催化剂用于乙酰化反应。
