Polymer compound and electroluminescent element

Abstract

There is provided a polymer compound in which a metal complex is bonded to a main chain of a polymer via a substituent for imparting a given distance therebetween. Specifically, a polymer compound is provided which has a partial structure represented by the general formula (1): It is thus rendered possible to improve the yield of synthesis of the polymer compound and to introduce a desired metal complex in a predetermined amount into the polymer compound. It is thus made possible to realize a white-light emitting material or a light emission of a desired color.
