Electronic structures,which play a key role in determining electrical and optical properties of π-conjugated organic materials,have attracted tremendous interest.Efficient thermoelectric(TE)conver-sion of organic materials has rigorous requirements on electronic structures.Recently,the rational design and precise modulation of electronic structures have exhibited great potential in exploring state-of-the-art organic TE materials.This review focuses on the regulation of electronic structures of organic mate-rials toward efficient TE conversion.First,we present the basic knowledge regarding electronic structures and the requirements for efficient TE conversion of organic materials,followed by a brief introduction of commonly used methods for electronic structure characterization.Next,we highlight the key strategies of electronic structure engineering for high-performance organic TE materials.Finally,an overview of the electronic structure engineering of organic TE materials,along with current challenges and future research directions,are provided.
