Complexation of copper(II) 2,3,9,10,16,17,23,24‐octahydroxy‐29H,31H‐phthalocyanine (CuPcOH) with copper(II) ions gives a two‐dimensional (2D) metal‐organic framework (MOF). This is the first report of a phthalocyanine‐based MOF. This 2D MOF was obtained as a black powder and showed an electrical conductivity of 1.6×10−6 S cm−1 at 80 °C. When this MOF is used as a cathode of lithium ion battery (LIB), large charge/discharge capacities of 151/128 mAh g−1 were obtained. In addition, it showed a good stability during 200 charge/discharge cycles. The obtained LIB performance mainly originates from the electrically conductive and redox‐active framework of the phthalocyanine‐based 2D MOF and its hierarchical microporous/mesoporous structure.
Complexation of the copper(II) phthalocyanine derivative, having four catechol moieties, with copper(II) ions gave a two‐dimensional MOF with hierarchical micro/mesoporous structure. The redox‐activity and conductivity of the framework rendered this Cu‐CuPc MOF a unique cathode material for the lithium‐ion battery system, showing large charge/discharge capacity with high cycle stability.
