Abstract:
1. A structure comprising: a substrate; a first layer formed on the substrate and comprised of a self-assembled monolayer comprising a compound represented by Formula (3) below; and a second layer which is formed on the first layer, is obtained by micro-phase separation of a block copolymer comprising a hydrophilic polymer comprised of polyethylene oxide and a hydrophobic polymer comprised of polymethacrylic acid comprising azobenzene at the side chain, comprises a cylinder phase with its long axis being oriented perpendicular to the substrate, and has a thickness T within a range of A≦T≦50 nm, where A is a phase separation period length satisfying 5 nm≦A≦50 nm: wherein Q2 is selected from the group consisting of a methylene group, a phenylene group, a naphthalene group, a divalent organic group comprising at least one methylene group, a divalent organic group comprising at least one phenylene group, and a divalent organic group comprising at least one naphthalene group, Ms2 is a mesogenic group represented by Formula (4A) or (4B) below: wherein R
