Polymerizable biaryls, process for their preparation and their use |
摘要 |
A process for preparing polymerizable biaryl derivatives comprises reacting an aromatic comprising a 6-membered ring which bears ester or benzylic OH groups in the 1,4 position with a second aromatic in a palladium-catalyzed cross-coupling reaction to give a biaryl and converting the ester or benzylic OH groups into polymerizable groups in one or more steps. The biaryls obtained are suitable for preparing polymers which are used as electroluminescence materials.
