摘要：

We report on a new polyfluorene derivative containing a spiroanthracenefluorene unit with a remote C-10 position that provides facile substitution of alkyl groups. An ethylhexyl group was introduced into the spiroanthracenefluorene unit and the ethylhexyl-substituted spiroanthracenefluorene was polymerized via an Ni(0)- mediated polymerization. The polymer showed a high spectral stability with respect to heat treatment, UV irradiation, and high current passage. A light-emitting device based on this polymer showed an emission in a deep blue region with CIE color coordinates of x = 0.17 and y = 0.12.
