Abstract:
An organic electroluminescence device obtained by forming either a light-emitting layer or a plurality of organic compound thin layers including the light-emitting layer between a pair of electrodes composed of a cathode and an anode, wherein at least one layer contains a compound having the formula (I), (II) or (III), ##STR102##wherein each of R.sup.1 to R.sup.6 is independently a non-substituted aryl group, a substituted aryl group, a non-substituted alicyclic group, a substituted alicyclic group, a non-substituted heterocyclic group or a substituted heterocyclic group, and each of X.sup.1 to X.sup.6 is independently an oxygen atom or a sulfur atom, or a nitrogen atom to which a hydrogen atom, methyl group, ethyl group or an aryl group is bonded, ##STR103##wherein each of R.sup.1, R.sup.2 and R.sup.4 to R.sup.11 is independently a non-substituted aryl group, substituted aryl group, non-substituted alicyclic group, a substituted alicyclic group, a non-substituted heterocyclic group or a substituted heterocyclic group, each of X.sup.1 to X.sup.12 is independently an oxygen atom or a sulfur atom or a nitrogen atom to which a hydrogen atom, methyl group, ethyl group or an aryl group is bonded, and A.sup.1 is a chemically rational organic residue which is composed of C, H and O or is composed of C, H, O and S, and has a molecular weight of 500 or less, ##STR104##wherein each of R.sup.1, R.sup.2, R.sup.4 to R.sup.11 and R.sup.13 to R.sup.17 is independently a non-substituted aryl group, substituted aryl group, non-substituted alicyclic group, a substituted alicyclic, a non-substituted heterocyclic group or a substituted heterocyclic group, each of X.sup.1 to X.sup.18 is independently an oxygen atom or a sulfur atom or a nitrogen atom to which a hydrogen atom, methyl group, ethyl group or an aryl group is bonded, and A.sup.2 is a chemically rational organic residue which is composed of C, H and O or is composed of C, H, O and S, and has a molecular weight of 500 or less,the thickness of each layer being in the range of from 10 nm to 0.2 .mu.m.
