Patent ID: 8476322

Claim:
A microphase-separated structure membrane comprising a block copolymer in which a hydrophilic polymer component and a hydrophobic polymer component are coupled to each other via a structural unit having a reactive group, wherein the hydrophilic polymer component is poly(ethylene oxide), the hydrophobic polymer component is poly(acrylate) or poly(methacrylate) having a mesogenic side chain; a cylinder structure composed of the hydrophilic polymer component lies in a matrix composed of the hydrophobic polymer component and said cylinder structure is oriented in the direction perpendicular to the membrane surface, and the structural unit having a reactive group lies between the matrix and the cylinder structure; and the structural unit having a reactive group is represented by any of the following formulae (5)-(12)and(14)-(32): (in the formulae, R 2 represents a reactive group; R 4 represents a cyano group or a carboxylic acid ester; Fu represents a fullerene; b and c may be the same or different and each represent an integer of 0 to 4; d represents an integer of 0 to 3; e, f, and g may be the same or different and each represent an integer of 1 to 10; Ar represents an aromatic hydrocarbon composed of a plurality of aromatic rings or a quinone; R 8 represents hydrogen, an aromatic hydrocarbon, or a heterocycle; M represents H 2 or a metal ion; ML represents a transition metal complex; Por represents a porphyrin; and X 2 represents hydrogen, a halogen, or a phenoxy group having an alkyl group, wherein the reactive group is selected from the group consisting of the followings: in the formulae, R 3 represents a hydrogen atom or an alkyl group)).
