- and a substituted or unsubstituted amine group;
- R1 to R3 are the same as or different from each other, and each independently selected from the group consisting of hydrogen;
- deuterium;
- a halogen group;
- a cyano group;
- a substituted or unsubstituted alkyl group;
- a substituted or unsubstituted alkenyl group;
- a substituted or unsubstituted alkynyl group;

- a substituted or unsubstituted heterocycloalkyl group;
- a substituted or unsubstituted aryl group;
- a substituted or unsubstituted heteroaryl group;
- a substituted or unsubstituted phosphine oxide group;
- and a substituted or unsubstituted amine group, or two or more groups adjacent to each other bond to each other to form a substituted or unsubstituted aliphatic or aromatic hydrocarbon ring or heteroring;
- R21 is hydrogen;
- or a substituted or unsubstituted aryl group,
- m, p, x, n, q and y are each an integer of 1 to 5;
- a is an integer of 1 to 3;
- b is an integer of 1 to 4;
