Organic electroluminescence device |
| abstract |
An organic electroluminescence device which has a pair of electrodes, at least one of which is transparent or semitransparent, and at least one organic layer formed between the electrodes. The organic layer contains a hole transporting material and a light emitting material in the same or different layer. The hole transporting material contains at least one polysilane whose main chain skeleton is composed of a repeating unit represented by the general formula (1) and a repeating unit represented by the general formula (2): wherein R1, R2, R3 and R4 independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group, Ar1 represents a substituted or unsubstituted arylene group and Ar2 represents a substituted or unsubstituted aryl group. The polysilane satisfies the expression 0.2</=z</=1 where a ratio of the number of the repeating unit (1) and that of the repeating unit (2) to the total number of the repeating units (1) and (2) are z and 1-z, respectively. The polysilane has a weight average molecular weight of not less than 5000 and a hole drift mobility of 10-3-10-1 cm2/v/sec. The organic EL device shows excellent characteristics of higher luminance and higher luminous efficiency at lower driving voltage. |
