This review focuses on functional materials that contain terpyridine (terpy) units, which can be synthesized from biomass-derived platform chemicals. The latter are obtained by the chemical conversion of raw biopolymers such as cellulose (e.g., 2-furaldehyde) or lignin (e.g., syringaldehyde). These biomass-derived platform chemicals serve as starting reagents for the preparation of many different terpyridine derivatives using various synthetic strategies (e.g., Kröhnke reaction, cross-coupling reactions). Chemical transformations of these terpyridines provide a broad range of different ligands with various functionalities to be used for the modification or construction of various materials. Either inorganic materials (such as oxides) or organic ones (such as polymers) can be combined with terpyridines to provide functional materials. Different strategies are presented for grafting terpy to materials, such as covalent grafting through a carboxylic acid or silanization. Furthermore, terpy can be used directly for the elaboration of functional materials via complexation with metals. The so-obtained functional materials find various applications, such as photovoltaic devices, heterogeneous catalysts, metal-organic frameworks (MOF), and metallopolymers. Finally, some possible developments are presented.
这篇综述聚焦于含有三吡啶（terpy）单元的功能材料，这些单元可以从生物质衍生的平台化学品中合成得到。这些平台化学品是通过对纤维素（例如 2-糠醛）或木质素（例如 丁香醛）等原始生物聚合物进行化学转化而获得的。这些生物质衍生的平台化学品可用作起始试剂，通过各种合成策略（例如，Kröhnke 反应、交叉偶联反应）制备许多不同的三吡啶衍生物。这些三吡啶的化学转化提供了广泛的具有不同功能的不同配体，可用于修饰或构建各种材料。无机材料（如氧化物）或有机材料（如聚合物）都可以与三吡啶结合，提供功能材料。介绍了将 terpy 接枝到材料上的不同策略，例如通过羧酸或硅烷化的共价接枝。此外，terpy 可以通过与金属配位直接用于功能材料的制备。所得的功能材料有各种应用，例如光伏器件、多相催化剂、金属有机框架（MOF）和金属聚合物。最后，提出了一些可能的发展方向。
