Patent ID: 7396598

Claim:
A polymer light-emitting material wherein the material has a light emitting mechanism based on transition from an excited triplet state to a ground state or transition through an excited triplet state to a ground state of an electron energy level, and the material comprises a nonionic light emitting part which constitutes a part of the polymer or is bound to the polymer, wherein said material is obtained by polymerizing a polymerizable composition containing at least one polymerizable light emitting compound represented by the formula (H-1) below: wherein R 1H and R 2H each independently represents a hydrogen atom, a halogen atom, a nitro group, an amino group, a sulfonic acid group, a sulfonic acid ester group or an organic group having 1 to 20 carbon atoms which may be substituted by a hetero atom, and R 3H represents a polymerizable substituent represented by (H-3):
