Phenanthrene and dihydrophenanthrene derivatives (I) with aromatic or heteroaromatic substituents are new. Phenanthrene derivatives of formula (I) are new. T : linear, branched or cyclic alkyl or alkoxy chain with 1-40C atoms (optionally substituted with R 11>; one or more non-adjacent C-atoms are optionally replaced by N-R 11>, O, S, O-CO-O, CO-O, -CR 11>=CR 11> or Ctriple boundC; and one or more H atoms are optionally replaced by F, Cl, Br, I or CN), 2-60C (hetero)aromatic ring (optionally substituted with one or more of R 11>), H or F; R 1>-R 4>T, H or F; either R 5>-R 10>T, H, F, Cl, Br or I; or 2(R 5>-R 10>) : mono or polycyclic ring system; X : -CR 11>=CR 11>-, -Ctriple boundC or -N(Y)-; Y : 2-60C (hetero)aromatic ring (optionally substituted with one or more of R 11>); either R 11>linear, branched or cyclic alkyl or alkoxy chain with 1-22C atoms (where one or more non-adjacent C-atoms are replaced by O, S, O-CO-O, CO-O, CH=CH or -Ctriple boundC; and one or more H-atoms are optionally replaced by F, Cl, Br, I or CN), (hetero)aryl-, (hetero)aryloxy with 5-40C atoms (optionally substituted with one or more non-aromatic groups of R 11>) or H; or 2R 11>, R 11>+R 1>-R 10>a ring system; n : 0 or 1; and m : 0-4. Provided that at least one of the two groups of R 1> and R 3> is not equal to H; R 2> and R 4> may together form phenanthrene system instead of dihydrophenanthrene system; at least one index of m is not equal to 0; and at least two of the substituents of R 1>-R 4> are not equal to H, when (I) represents tetrahydropyrene system. Independent claims are also included for: (1) a mixture of at least (I) either with a host material or with a dopant; and (2) organic electronic devices containing anode, cathode and (I) with mixture.
