摘要:
An organic electroluminescence device including an oxadiazole or thiadiazole compound interposed between two electrons. The compound is of the formula ##STR1## wherein Z.sup.1 and Z.sup.2 are each an unsubstituted or substituted aromatic group; Y.sup.1 and Y.sup.2 are each an unsubstituted or substituted aromatic group; Q is --O--, --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --; or --C(CH.sub.3).sub.2 ; and X is --O-- or --S--. The organic electroluminescence device has a high brightness, a high luminous efficiency and a long service life.
