COMPOSITE MATERIAL CONTAINING COF, HEAT DISSIPATION/STORAGE MEMBER, AND PRODUCTION METHOD FOR SAID COMPOSITE MATERIAL, AND COF MONOCRYSTAL AND PRODUCTION METHOD THEREFOR

摘要

The composite material according to the present invention contains a monocrystal of a covalent organic framework (COF) having a longitudinal axis greater than 120 μm in length or a COF polycrystal including a plurality of the monocrystals, and at least one heat-storing compound. The heat-storing compound generates or absorbs heat due to such as being adsorbed to or desorbed from the COF monocrystal. In addition, the heat dissipation/storage member according to the present invention contains the composite material as a heat storage/heat dissipation material. Furthermore, the COF monocrystal according to the present invention has a longitudinal axis greater than 120 μm in length. The production method for a COF monocrystal according to the present invention is for growing a monocrystal of a COF by crystallizing a raw material compound for the COF by using an ionic liquid, or a solution containing an organic salt and an equilibrium regulation agent.
