<p>Disclosed is a polymer material containing a fluorescent or phosphorescent compound. When used in a light-emitting device, the polymer material enables to obtain a light-emitting device with excellent practicability which can be driven at low voltage and is excellent in luminous efficiency, color tones of emitted light and the like. Specifically disclosed is a polymer material characterized by containing a polymer (A) having a residue of a compound represented by the formula (1) below or the structure of (A), and a molecule (B) exhibiting fluorescence or phosphorescence in the visible region or the structure of (B). (1) (In the formula, ring A, ring B and ring C independently represent an optionally substituted aromatic ring or non-aromatic ring; and Z1, Z2, Z3, Z4 and Z5 independently represent C-(Q)z or a nitrogen tom, wherein Q represents a substituent or a hydrogen atom and z represents 0 or 1. The ring A and ring B may have in common an atom other than Z5 in the rings, and one or two of the ring A, ring B and ring C are non-aromatic rings.)</p> |
