SINGLE TRIPHENYLENE CHROMOPHORES IN PHOSPHORESCENT LIGHT EMITTING DIODES

Novel triphenylene compounds are provided. Specific examples include multi-aryl-substituted triphenylenes. A preferred group of compounds are triphenylenes that are substituted with a non-fused aryl group having one or more meta-substituents, where each meta-substituent is a non-fused aryl group optionally substituted with further substituents selected from the group consisting of non-fused aryl groups and alkyl groups. A further preferred group of compounds are triphenylenes that are substituted with a non-fused heteroaryl group having one or more meta-substituents, where each meta-substituent is a non-fused aryl or heteroaryl group optionally substituted with further substituents selected from the group consisting of non-fused aryl groups, non-fused heteroaryl groups, and alkyl groups. Some high triplet energy analogs are expected to work with deep blue phosphorescent dopants. The compounds may be useful in phosphorescent organic light emitting devices. Also provided is an organic electroluminescent device comprising an anode, a cathode, and an emissive layer between the anode and the cathode, the emissive layer comprising a phosphorescent material and a compound having a repeat unit, the repeat unit containing a triphenylene moiety.

Studies of Polyphenyls and Polyphenylenes. II. The Synthesis and Physical Properties of Polyphenyls Containing Para Linkage

Twelwe linear polyphenyls, including quinque- to octiphenyl, were synthesized by the Ullmann cross-coupling reaction of iodobiphenyl with diiodobenzene or iodoterphenyl.Ultraviolet spectral studies of the polyphenyls indicated that the positions of the K-bands above ca.260 nm, regardless of the presence of o- or m-phenylene unit(s), may be considered to be an indication of the approximate number of consecutive p-phenylene units.Infrared studies also showed that the locations of strong or medium bands in the 815-850 cm-1 region may give the same information.The HMO calculations of the longest wavelength absorption bands of twenty-four polyphenyls were carried out.A comparison between the calculated and observed wavelengths gave rather good agreement, except in the cases of two compounds.The signals of the proton magnetic resonanse spectra of eighteen polyphenyls were assigned tentatively.The correlations between the arrangement of the benzene rings and the spectral patterns are discussed.
