Japanese Patent JP5661982

B2

The present invention provides a luminescent composition comprising a polymer and at least one type of phosphorescent compound, wherein (a) a minimum repeat unit of the polymer is represented by any one of formulae (3-1) to (3-13) as defined herein, and the electron conjugated chain coefficient Z e of a major and minimum repeat unit of the polymer falls within the following range: 0 < Z e ‰¤ 2.00 where the electron conjugated chain coefficient Z e is defined as the slope of a linear approximation line of the following function in accordance with the least-squares method: T m = T m 1 / n e where n e is the number of conjugated electrons contained in a minimum repeat unit; and T m is the lowest triplet excitation energy of an m-multimer obtained by connecting the minimum repeat units where m alters from 1 to 3 by 1's, with the proviso that the number of conjugated electrons is limited to that of conjugated electrons present in the main chain of the minimum repeat unit; and when a plurality of major and minimum repeat units are present, the lowest Z e is used; or (b) the major and minimum repeat unit of the polymer is represented by the formula (4) as defined herein; or (c) the luminescent composition is a luminescent material containing a luminescent polymer which contains a luminescent compound in the same molecule, as a partial structure, wherein a polymer having an electron conjugated chain coefficient Z e of the major and minimum repeat unit falling within the range above is further contained, or the electron conjugated chain coefficient Z e of the luminescent polymer falls within the range above.
