摘要： The present invention relates to an organic-inorganic hybrid nanoporous material, maintaining a nanoporous skeleton structure formed by coordination of an organic ligand containing an aromatic compound to a trivalent central metal ion, and further having an intramolecular acid anhydride functional group modified on the aromatic compound of the nanoporous skeleton structure, and thereby exhibits selectivity for olefins, and an adsorbent comprising the same. Specifically, the organic-inorganic hybrid nanoporous material of the present invention exhibits an excellent olefin-selective adsorption capacity through differences in adsorption equilibrium and adsorption rate, and thus can be usefully employed in the separation of C2-C4 hydrocarbons. Further, the olefins adsorbed to the organic-inorganic hybrid nanoporous material can be desorbed by purging of an inert gas which is not liquefied by way of mild vacuum conditions or compression, and thus, the organic-inorganic hybrid nanoporous material can be used to prepare olefins by separating C2-C4 hydrocarbon mixtures.
