Ionic　covalent　organic　frameworks　(iCOFs),　a　subset　of　burgeoning　COFs　materials　featuring　both　charged　sites　and　ordered　frameworks,　have　been　increasingly　recognized　due　to　their　unique　properties　and　unrivaled　potential　in　a　plethora　of　energy　functionalities.　However,　current　progress　on　the　applications　of　iCOFs　for　various　energy　aspects　have　not　been　comprehensively　overviewed.　Facing　the　prosperous　growth　of　iCOF　fields,　the　review　exploring　the　seminal　advanced　electro-,　photo-,　and　thermo-　energy　functionalities　of　iCOFs　are　presented　here.　Beginning　with　a　reflection　on　the　classification　and　building　units　of　iCOFs,　the　construction　principles　employed　for　iCOFs　are　elucidated.　Then　the　state-of-the-art　advancements　of　iCOFs　in　electricity　generation　and　storage　devices　are　summarized.　And　meanwhile,　the　functionalities　in　photo-induced　energy　conversion　as　well　as　thermal　energy　management　systems　are　coordinately　focused.　Further,　the　concise　discussions　regarding　to　the　intricate　relationship　between　the　ionic　structure　and　multifarious　functions　within　iCOFs　are　delved.　Finally,　a　comprehensive　analysis　on　both　opportunities　available　to　iCOFs　and　challenges　they　face　currently　are　conducted.　The　insights　from　this　review　pave　the　way　for　the　fabrication　of　next-generation　high-performance　iCOFs　and　open　new　perspectives　for　their　extensive　industrial　applications.　©　2024
