The unique properties of natural tetrapyrrolic compounds have inspired the rapid growth of research interest in the design and synthesis of artificial porphyrinoids and their metal complexes as a basis of modern functional materials. A special role in the design of such materials is played by sandwich complexes formed by tetrapyrrolic macrocycles with rare earth elements, especially lanthanides. The development of synthetic approaches to the functionalization of tetrapyrrolic compounds and their rare earth complexes has facilitated the intensive development of new applications over the last decade. As a way of expanding the functionalities of rare earth complexes, sophisticated examples have been obtained, including mixed-ligand complexes, π-extended analogues, covalently linked and fused sandwiches, complexes with less-common tetrapyrrols, sandwiches with non-tetrapyrrolic macrocycles and even complexes containing up to six stacked ligands. This review intends to offer a general overview of the preparation of such sophisticated REE tetrapyrrolic sandwiches over the last decade as well as emphasizes the current challenges and perspectives of their application in areas such as single-molecule magnetism (SMM), organic field-effect transistors (OFET), conductive materials and nonlinear optics (NLO).

稀土基四吡咯三明治：化学、材料和应用

天然四吡咯化合物的独特性质激发了人们对设计和合成人造卟啉及其金属配合物作为现代功能材料基础的研究兴趣的快速增长。四吡咯大环化合物与稀土元素，尤其是镧系元素形成的三明治复合物在此类材料的设计中起着特殊的作用。在过去十年中，四吡咯化合物及其稀土配合物功能化合成方法的发展促进了新应用的深入发展。作为扩展稀土配合物功能的一种方式，已经获得了复杂的例子，包括混合配体配合物、π-扩展的类似物、共价连接和融合的三明治、具有不太常见的四吡咯的配合物，具有非四吡咯大环化合物的三明治，甚至包含多达六个堆叠配体的复合物。这篇综述旨在概述过去十年中这种复杂的 REE 四吡咯三明治的制备，并强调当前的挑战和它们在单分子磁性 (SMM)、有机场效应晶体管等领域的应用前景(OFET)、导电材料和非线性光学 (NLO)。
