| 摘要 | This invention provides a luminescent composition comprising a polymer and at least one phosphorescent compound, characterized in that the electronic conjunction chain coefficient Ze of the main repeating minimum unit of the polymer falls within the following range: 0<Ze≦2.00 (1) wherein the electronic conjunction chain coefficient Ze is defined as a slope obtained by linear approximation of function Tm=Tm(1/ne) by the least square method wherein ne represents the number of conjugated electrons contained in repeating minimum units; and Tm represents, for m-mer obtained by bonding repeating minimum units, the lowest triplet excitation energy in each m-mer when the number m is varied from 1 to 3 by one by one. Here in the number of conjugated electrons, only the conjugated electrons present in the main chain of the repeating minimum units are taken into consideration, provided that, when there are a plurality of main repeating minimum units, the minimum Ze is used. | ||
