    Abstract: Compounds exhibiting high hole mobility and/or high glass transition temperatures are provided which are of the formula [Ar1]m[Ar2]n wherein: m is an integer from 1-3 and n is an integer and may be 1 or 2; Ar1 represents a thianthrene residue having a linkage to Ar2 at one or two positions selected from ring positions 1-4 and 5-8 and optionally mono-, bi- or poly-substituted with C1-C4-alkyl-, C1-C4-alkoxy-, fluoro, phenyl or biphenyl which in the case of phenyl or biphenyl may be further substituted with C1-C4-alkyl-, C1-C4-alkoxy- or fluoro; Ar2 represents a residue derived from an arylamine in which the aryl rings are phenyl, naphthyl or anthracenyl optionally substituted with C1-C4-alkyl-, C1-C4-alkoxy- or fluoro, a polycyclic fused or chain aromatic ring system optionally containing nitrogen or sulphur and in a chain aromatic ring system optionally containing one or more chain oxygen or sulphur atoms, a triarylphosphine oxide or an arylsilane the rings of any of which are optionally substituted with C1-C4-alkyl-, C1-C4-alkoxy- or fluoro. Certain of the compounds may be used in electron transport layers and may be doped with p-type dopants. They may be incorporated into OLEDs, organic photovoltaic devices, imaging members and thin film transistors.In further embodiments there are provided OLEDs or other devices e.g. electrostatic latent image forming members in which improved efficiency is obtained by using as electron transport layers, electron injectors, hosts and emitters (dopants) ambipolar or electron-transmitting compounds in which thianthrene is bonded to aryl e.g. 1-anthracenyl-9-yl-thianthrene, 1-biphenyl-4-yl-thianthrene and 9,10-Bis(1-thianthrenyl) anthracene.
