Provided that, if the ring formed from R3 and R4 of phenyl moiety of formula (a) by linkage via alkylene or alkenylene is benzene, the ring formed from R7 and R8 of -C(R7)=C(R8)- by linkage via alkylene or alkenylene is not benzene. An INDEPENDENT CLAIM is also included for an organic electronic device comprising a first electrode, second electrode, and at least one organic layer(s) interposed between the first electrode and the second electrode, where the organic layer comprises an electroluminescent region comprising (I) and a host, which comprises 1,3,5-tricarbazolylbenzene, polyvinylcarbazole, meta-biscarbazolyl phenyl, 4,4',4''-tri(N-carbazolyl)triphenylamine, 1,3,5-tri(2-carbazolylphenyl)benzene, 1,3,5-tris(2-carbazolyl-5-methoxyphenyl)benzene or bis(4-carbazolylphenyl)silane, or biphenyl compound of formula (II), phenyl-benzothiazole aluminum complex compound of formula (III), 2-methyl-quinoline aluminum complex compound of formula (IV) or (L1L2M1(Q)y) (V).    either R91-R94 = T; or    each of R91-R94 linked to an adjacent substituent via (3-60C)alkylene or (3-60C)alkenylene with or without a fused ring = form an alicyclic ring, or a monocyclic or polycyclic aromatic ring, where the alkenyl, alkynyl, (cyclo)alkyl, heterocycloalkyl, (hetero)aryl, arylsilyl, alkylsilyl, alkylamino or arylamino, and the alicyclic ring, or the monocyclic or polycyclic aromatic are substituted by T;    L1, L2 = phenyl group of formula (b) or (c);    M1 = bivalent or trivalent metal; either    y = 0, when M1 is a bivalent metal; or    y = 1, when M1 is a trivalent metal;    Q = (6-60C)aryloxy or tri(6-60C)arylsilyl (both are substituted by (1-60C)alkyl or (6-60C)aryl);    X = O, S or Se;    ring A = oxazole, thiazole, imidazole, oxadiazole, thiadiazole, benzoxazole, benzothiazole, benzimidazole, pyridine or quinoline; either    R101-R104 = T; or    each of R101-R104 linked to an adjacent substituent via (3-60C)alkylene or (3-60C)alkenylene with or without a fused ring = form an alicyclic ring, or a monocyclic or polycyclic aromatic ring, where ring A or the alkenyl, alkynyl, (cyclo)alkyl, heterocycloalkyl, (hetero)aryl, arylsilyl, alkylsilyl, alkylamino or arylamino, and the alicyclic ring, or the monocyclic or polycyclic aromatic are substituted by T; and    ring B1 = pyridine or quinoline (both are substituted by (1-60C)alkyl), or phenyl or naphthyl (with or without (1-60C)alkyl substituent(s)).
