Abstract: front page image
(EN)A polymeric material which comprises either a composition comprising a fluorescent conjugated polymer (A) and a phosphorescent compound (B) or a polymer having the structure of the polymer (A) and the structure of the compound (B) in the same molecule, characterized by satisfying the following requirements (1), (2), and (3). (1) The fluorescent conjugated polymer (A) has one or more luminescent peaks at wavelengths at least one of which is shorter than 500 nm. (2) The phosphorescent compound (B) has a luminescent peak at a wavelength of 500 nm or longer. (3) The ingredients (A) and (B) satisfy the following relationship: ETA-ESA0 ≥ (ETB-ESB0) - 0.2 (unit: eV) (Eq. 1) (wherein ESA0 represents the energy of the fluorescent conjugated polymer (A) in the ground state; ETA represents the energy of the fluorescent conjugated polymer (A) in the minimum excited triplet state; ESB0 represents the energy of the phosphorescent compound (B) in the ground state; and ETB represents the energy of the phosphorescent compound (B) in the minimum excited triplet state).
(FR)L’invention concerne un matériau polymère comprenant soit une composition contenant un polymère conjugué fluorescent (A) et un composé phosphorescent (B) soit un polymère ayant la structure du polymère (A) et la structure du composé (B) dans la même molécule, caractérisé en ce qu’il satisfait aux exigences suivantes (1), (2), et (3). (1) Le polymère conjugué fluorescent (A) possède un ou plusieurs pics luminescents à certaines longueurs d’onde dont au moins une est inférieure à 500 nm. (2) Le composé phosphorescent (B) possède un pic luminescent à une longueur d’onde supérieure ou égale à 500 nm. (3) Les ingrédients (A) et (B) satisfont à la relation suivante : ETA-ESA0 ≥ (ETB-ESB0) - 0,2 (unité : eV) (Eq. 1) (où ESA0 représente l’énergie du polymère conjugué fluorescent (A) à l’état de base : ETA représente l’énergie du polymère conjugué fluorescent (A) à l’état triple excité minimal ; ESB0 représente l’énergie du composé phosphorescent (B) à l’état de base ; et ETB représente l’énergie du composé phosphorescent (B) à l’état triple excité minimal).
(JA)蛍光性共役系高分子(A)と、燐光性化合物(B)とを含む組成物を含有するか、または該(A)の構造と該(B)の構造とを同一分子内に有する高分子を含有する高分子材料であって、以下の(1)、(2)および(3)の条件を満たすことを特徴とする高分子材料。(1)蛍光性共役系高分子(A)の発光ピーク波長の少なくとも1つが500nm未満である(2)燐光性化合物(B)の発光ピーク波長が500nm以上である(3)下式の関係を満たす ETA−ESA0≧(ETB−ESB0)−0.2 (単位;eV)   (Eq1) (式中、ESA0は、蛍光性共役系高分子(A)の基底状態のエネルギーを表し、ETAは蛍光性共役系高分子(A)の最低励起三重項状態のエネルギーを表し、ESB0は燐光性化合物(B)の基底状態のエネルギーを表し、ETBは燐光性化合物(B)の最低励起三重項状態のエネルギーを表す。)
