Abstract: Disclosed are an alkyl-linked porous porphyrin polymer and gas separation and valuable metal recovery using the same, and more particularly an alkyl-linked porous porphyrin polymer imparted with a large surface area and high microporosity by linking a porphyrin unit with a chlorinated solvent linker, thereby exhibiting excellent adsorption selectivity for valuable metal to thus enable recovery of valuable metal, and also manifesting high performance in a selective gas separation method, and a method of separating gas and a method of recovering valuable metal using the same.

Abstract: Solvent-linked porous covalent organic polymers (COPs) and a method of preparing the same are described. The porous covalent organic polymers are linked by a solvent and are thus suitable for the transportation and storage of natural gas. A method of preparing the porous covalent organic polymers by conducting alkylation polymerization between an aromatic monomer and a chlorine-based solvent in the presence of a Lewis acid catalyst is described. Porous stretchable covalent organic polymers having pores with various sizes can be synthesized simply and quickly at room temperature and atmospheric pressure without a heating or purification step. The covalent organic polymers have very high natural gas storage capacity due to the flexible porous network structure thereof and thus are suitable for storage and transportation of natural gas and useful as a natural gas adsorbent.
