Copolymères conjugués à blocs pour diodes électroluminescentes

In this article we review results obtained in our laboratory on the design and study of new light-emitting polymers. We are interested in the synthesis and characterisation of block copolymers with regularly alternating conjugated and non conjugated sequences. The blocks giving rise to luminescence are pi-conjugated oligomers like oligo(thiophene)s, which are linked by non pi-conjugated oligomers for example oligo(silanylene)s. Colour tuning is achieved through precise control of the length of the conjugated blocks
