Polymer complex compound and polymer light emitting device using the same

摘要

A polymer complex compound comprising a repeating unit of the following formula (1) and a metal complex structure showing light emission from triplet excited state, having visible light emission in the solid state, and having a polystyrene reduced number-average molecular weight of 10³ to 10⁸: (wherein, Ring P and Ring Q each independently represent an aromatic ring, but Ring P may be either existent or non-existent. When Ring P is existent, two connecting bonds respectively are on Ring P and/or Ring Q, and when Ring P is non-existent, two connecting bonds respectively are on 5 membered ring containing Y, and/or Ring Q. Y represents -O-, -S- and the like).
