Abstract: A composite material including a covalent organic framework (COF) single crystal having a major axis length of larger than 120 μm or a COF polycrystal including a plurality of the single crystals, and at least one heat-storage compound. The heat-storage compound is a compound that generates heat or absorbs heat by adsorption to or desorption from the COF single crystal. Also, a heat dissipation/storage member containing the composite material as a heat storage/dissipation material a COF single crystal having a major axis length of larger than 120 μm, and a method for producing a COF single crystal by crystallizing COF raw material compounds via a solution containing an ionic liquid or an organic salt and an equilibrium adjusting agent to grow a COF single crystal.
