Abstract
An azo compound is represented by formula (1A). L1 and L2 each represent a divalent linking group or a single bond. y represents 1 or 2. p and q each represent 0 or 1, and at least one of p and q is 1. X represents an oxygen atom or NR5, and R5 represents a hydrogen atom or an aliphatic hydrocarbon group. R12, R13, and R14 each represent an aliphatic hydrocarbon group, and may each have a polymerizable group. Q represents a single bond or a group selected from —OC(═O)—, —C(—O)O—, —C═C—, —CH═CH—, —N═N—, —NHC(═O)—, and —C(═O)NH—. Ar1, Ar2, and Ar3 each represent a 1,4-phenylene group or a divalent sulfur-containing aromatic heterocyclic group. When y is 2, two Ar3s may be the same or different.
Claims9
An azo compound represented by the following formula (1):
- wherein in formula (1), L represents a divalent linking group or a single bond formed from at least one selected from the group consisting of a methylene group, an oxygen atom, and a carbonyl group;
- y represents an integer of 1 or 2;
- R1 represents one group selected from the group consisting of a methylamino group, an ethylamino group, a dimethylamino group, a diethylamino group, an ethylmethylamino group, a pyrrolidyl group, an oxazolidinyl group, a piperidyl group, a morpholino group, a methoxy group, and an ethoxy group, and a hydrogen atom of each of these groups may be replaced with a polymerizable group;
- R2, R3, and R4 each independently represent an aliphatic hydrocarbon group having 1 to 10 carbon atoms, and a hydrogen atom of R2, R3, or R4 may be replaced with a polymerizable group;
- Q represents one group selected from the group consisting of —OC(═O)—, —C(═O)O—, —C═C—, —CH═CH—, —N═N—, —NHC(—O)—, and —C(═O)NH—;
- Ar1, Ar2, and Ar3 each independently represent a 1,4-phenylene group optionally having a substituent or a divalent sulfur-containing aromatic heterocyclic group optionally having a substituent;
- and
- when y is 2, two Ar3 may be the same or different.
