Each monomer of the present application exhibits an excellent self-assembling property and is capable of forming a block copolymer to which a variety of required functions are granted as necessary without constraint.
Claims16
A block copolymer comprising a first block having a structural unit represented by Structural Formula 1 below:
- wherein R represents a hydrogen atom or an alkyl group;
- X represents an oxygen atom, a sulfur atom, —NR1—, —S(═O)2—, a carbonyl group, an alkylene group, an alkenylene group, an alkynylene group, —C(═O)—X1— or —X1—C(═O)—, wherein the X1 represents a single bond, an oxygen atom, a sulfur atom, —NR1—, —S(═O)2—, an alkylene group, an alkenylene group or an alkynylene group, wherein the R1 represents a hydrogen atom or an alkyl group;
- and
- Y represents an aryl group substituted with at least one of a substituent -Q-P, wherein the Q represents —K—C(═O)—X2—, —X2—C(═O)—K— or a cycloalkylene group, and the P represents a chain that contains 3 or more chain-forming atoms, wherein the X2 represents an oxygen atom, a sulfur atom, —S(═O)2—, an alkylene group, an alkenylene group or an alkynylene group, the K represents a linear or branched alkenylene group.
A block copolymer comprising a first block having a structural unit represented by Structural Formula 1 and a second block which has an aromatic structure that includes one or more halogen atoms
- wherein R represents a hydrogen atom or an alkyl group;
- X represents a single bond, an oxygen atom, a sulfur atom, —NR1—, —S(═O)2—, a carbonyl group, an alkylene group, an alkenylene group, an alkynylene group, —C(═O)—X1— or —X1—C(═O)—, wherein the X1 represents a single bond, an oxygen atom, a sulfur atom, —NR1—, —S(═O)2—, an alkylene group, an alkenylene group or an alkynylene group, wherein the R1 represents a hydrogen atom or an alkyl group;
- and
- Y represents an aryl group substituted with at least one of a substituent -Q-P, wherein the Q represents —K—C(═O)—X2—, —X2—C(═O)—K— or a cycloalkylene group, and the P represents a chain that contains 3 or more chain-forming atoms, wherein the X2 represents an oxygen atom, a sulfur atom, —S(═O)2—, an alkylene group, an alkenylene group or an alkynylene group, the K represents an alkenylene group.
