Abstract
A diacetylene-based polymer of the following formula (I): wherein, Ar represents a light emitting group. The present invention also provides an electroluminescence device having a structure of anode/luminescent layer/cathode added with a transfer layer and/or a reflection layer, if necessary, in which the luminescent layer is made of the diacetylene-based polymer containing the light emitting group. The polymer of the present invention can be easily blended with a variety of macromolecules for general use.
