Phthalocyanine　(Pc),　a　macrocyclic　aromatic　compound,　has　attracted　extensive　attention　in　energy　storage　due　to　its　large　π-conjugated　structure　and　abundant　nitrogen　sites.　However,　the　poor　solubility　of　Pc　monomers　leads　to　rigorous　polymerization　conditions,　which　hinder　the　application　and　development　of　Pc-based　polymers.　Herein,　1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile　(HAT(CN)6)　is　used　as　a　precursor　to　construct　Pc-based　conjugated　polymers　(Pc-COPs)　via　a　molten　salt　assisted　strategy.　The　physical-chemical　properties　of　the　resulting　Pc-COPs　at　different　synthesis　temperatures　were　systematically　studied,　which　indicates　that　Pc-COP-350　(at　the　synthesis　temperature　of　350　°C)　exhibits　complete　polymerization　while　maintaining　the　redox　activity　of　the　active　centers.　As　the　cathode　material　for　aqueous　zinc-ion　batteries,　Pc-COP-350　exhibited　the　best　electrochemical　performance,　achieving　a　specific　capacity　of　269　mA　h　g-1　at　0.05　A　g-1.　The　Coulombic　efficiency　is　up　to　nearly　100%　even　after　long　cycles　at　a　current　density　of　1　A　g-1.　This　work　provides　a　pathway　for　designing　and　synthesizing　Pc-based　macrocyclic　compounds.　©　2024　American　Chemical　Society.
