The polymer light-emitting material for an organic electroluminescent device is obtained by subjecting a thermoplastic resin having an Mw of 2,000-1,000,000 and containing a functional group in a unit constituting the backbone and a metal-containing phosphorescent dopant compound containing a reactive group capable of reacting with the said functional group to a polymer reaction so as to link a phosphorescent dopant moiety derived from the metal-containing phosphorescent dopant compound to the unit constituting the backbone of the thermoplastic resin. The content of the metal derived from the metal containing phosphorescent dopant compound in the said polymer light-emitting material is 0.001-20 wt %.Type: GrantFiled: February 25, 2010Date of Patent: March 22, 2016Assignee: NIPPON STEEL & SUMIKIN CHEMICAL CO., LTD.Inventors: Hiroshige Tanaka, Takaya Ishiyama, Kazuto Shiraishi, Tohru Asari, Hiroyuki Hayashida, Kazuaki Yoshimura
