Thermoelectric (TE) materials are emerging as an attractive and promising candidate for solving the energy crisis in which waste heat is efficiently recycled to generate electricity. In order to realize high thermoelectric energy conversion, an ideal TE material should present high electrical conductivity and Seebeck coefficient, but low thermal conductivity. In recent years, conducting coordination polymers have been recognized as new promising organic materials for TE uses, as they bear the advantages of both inorganic and organic materials: proper integration of metal centers helps to enhance the electrical conductivity, while organic backbones are always heat insulators. Herein, a variety of TE metallopolymers are highlighted and their TE properties as well as the related physical factors are discussed in detail. To the best of current knowledge, the highest figure of merit (ZT) value of p‐type organic polymers to date has reached 0.42, and by comparison, an Ni‐based polymer, poly(Ni‐ett) (ett = 1,1,2,2‐ethenetetrathiolate), is the only n‐type TE material possessing a ZT value comparable to those of PEDOT‐based p‐type counterparts (PEDOT, poly(3,4‐ethylenedioxythiophene)). Based on the current achievements, a promising blueprint is displayed to boost up the further development of metallopolymer‐based organic TE materials in the near future.

导电金属聚合物在有机热电领域的新兴应用
热电（TE）材料正成为解决能源危机的诱人和有前途的候选者，在能源危机中，废热得以有效回收以发电。为了实现高的热电能量转换，理想的TE材料应具有高的电导率和塞贝克系数，但应具有低的热导率。近年来，导电配位聚合物由于具有无机和有机材料的优点而被公认为是新型有前景的有机材料，因为它们同时具有无机和有机材料的优点：金属中心的适当结合有助于提高导电性，而有机主链始终是绝热体。在本文中，重点介绍了多种TE金属聚合物，并详细讨论了它们的TE特性以及相关的物理因素。迄今为止，p型有机聚合物的ZT）值已达到0.42，相比之下，仅有的n-是基于镍的聚合物聚（Ni-ett）（ett = 1,1,2,2-乙撑四硫醇酯）。 TE型材料的ZT值可与基于PEDOT的p型对应物（PEDOT，聚（3,4-乙撑二氧噻吩））相媲美。根据当前的成就，将展示出一个有希望的蓝图，以促进在不久的将来基于金属聚合物的有机TE材料的进一步发展。
