Progress in molecular organic electroluminescent materials

Efficient electroluminescence from sublimated organic films at low voltage was first reported in 1987. Since then, an important volume of academic and industrial research has been realized in order to develop new efficient ma terials with high life time but also to optimize the technological steps of the devices fabrication. So, in this paper, the best known materials to da te are described. (C) 2000 Academie des sciences/Editions scientifiques et medicales Elsevier SAS.
