The present invention relates to an organic electronic device, comprising a first electrode, a second electrode, and a substantially organic layer comprising a compound according to formula (I) between the first and the second electrode: wherein A1 is a C6-C20 arylene and each of A2-A3 is independently selected from a C6-C20 aryl, wherein the aryl or arylene may be unsubstituted or substituted with groups comprising C and H or with a further LiO group, provided that the given C count in an aryl or arylene group includes also all substituents present on the said group.
