Derivatives of newly synthesized aromatic polyimides containing sulphur atoms in the backbone were studied as electron–hole‐transporting and light‐emitting materials for use in combination with tris(8‐hydroxyquinoline)‐aluminium in multilayer organic electroluminescent devices. Efficient bipolar charge transport has been revealed in the polymers. Bright electroluminescence (15000cdm ‐2 at 14V) was observed in the visible range. The possible role of intermolecular donor–acceptor interactions in the mechanism of electroluminescence is discussed. © of SCI.
