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).
(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 atom, 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.)
本发明公开了一种含有荧光或磷光化合物的聚合物材料。该聚合物材料用于发光器件时,可获得实用性极佳的发光器件,该器件可在低电压下驱动,并且在发光效率、发射光的色调等方面性能优异。具体地说,本发明公开了一种高分子材料,其特征在于,该材料包含具有下式(1)所代表化合物残留物或(A)结构的聚合物(A),以及在可见光区域显示荧光或磷光的分子(B)或(B)结构。
(式中,环 A、环 B 和环 C 独立地代表任选取代的芳香环或非芳香环;Z1、Z2、Z3、Z4 和 Z5 独立地代表 C-(Q)z 或氮原子,其中 Q 代表取代基或氢原子,z 代表 0 或 1。环 A 和环 B 中可以有一个除 Z5 以外的原子,并且环 A、环 B 和环 C 中的一个或两个是非芳香环。)
