There is provided a metalloporphyrin complex represented by general formula (1): 

Metalloporphyrin complex, manufacturing process therefor and carbon dioxide fixation catalyst therefrom, as well as process for manufacturing cyclic carbonate

Disclosed is an organic-inorganic composite material obtained by chemically modifying a microorganism-derived ceramic material with an organic group, and a process for producing the organic-inorganic composite material. The process is characterized by reacting a microorganism-derived ceramic material with at least one compound selected from the group consisting of silane coupling agents represented by formula (1), silane coupling agents represented by formula (2), and titanate coupling agents represented by formula (3). The organic-inorganic complex can be used in applications for immobilized catalysts and immobilized enzyme catalysts.

A novel optical-isomer separating agent for chromatography is provided which has, as a chiral selector, a macrocyclic amide compound having the ability to function as a chiral shift agent. The optical-isomer separating agent for chromatography is formed by bonding, with a carrier by chemical bonding, a specific ring structure containing an asymmetry recognition site, an amide group as a hydrogen-bond donor site, and a hydrogen-bond acceptor site.
