ANTHRACENE DERIVATIVES AND ORGANIC ELECTROLUMINESCENT DEVICES MADE BY USING THE SAME

An anthracene derivative represented by the following general formula (1) which enables an organic electroluminescence device to exhibit a great efficiency of light emission and uniform light emission even at high temperatures since crystallization is suppressed and no thermal decomposition takes place during vapor deposition and an organic electroluminescence device utilizing the derivative, are provided. [Ar represents a group represented by the following general formula (2): (L1 and L2 each represent a substituted or unsubstituted methylene group, ethylene group or the like, and at least one of them is present), Ar' represents a substituted or unsubstituted aryl group having 6 to 50 nuclear carbon atoms, X represent an alkyl group or the like, a and b each represent an integer of 0 to 4, and n represents an integer of 1 to 3.]

Vapor-phase oxidation and oxidative ammonolysis of some methyl derivatives of biphenyl

Main pathways arc established of catalytic oxidative transformations of 3,4-di- and 3,3',4,4'-tetramethylbiphenyls in vapor phase. The possibility is analyzed of obtaining the corresponding anhydrides, imides, and nitriles of biphenylcarboxylic acids in yields of up to 59-69%.

Formation of cyclopent[a]indene and acenaphthylene from allyl esters of biphenyl mono- and di-carboxylic acids and from biphenyl dicarboxylic anhydrides on flash vacuum pyrolysis at 1000-1100°C

Flash vacuum pyrolysis at 1000-1100°C of the allyl esters of the three isomeric biphenylcarboxylic acids, of the allyl esters of the 12 biphenyldicarboxylic acids and of the three biphenyldicarboxylic anhydrides gave pyrolysates which were examined by 1H n.m.r. spectroscopy at temperatures below -50°C. In all cases the spectra showed the presence of cyclopent[a]indene and acenaphthylene together with other products. Possible mechanisms for these ring contraction and cyclization processes are discussed and the results of pyrolyses of [2,3-13C2]biphenyl-2,3-dicarboxylic anhydride, and [3,4-13C2]-and (2-2H1)-biphenyl-3,4-dicarboxylic anhydrides are reported.

Ashless additives for lubricating compositions

Superior ashless additives for lubricants are prepared by a process comprising first introducing a petroleum sulfonic acid and a polyamine to a reaction zone and subsequently introducing a cyclic anhydride of a dicarboxylic acid into the reaction zone. In another embodiment, the solids content of the additives is reduced to acceptable levels by removal of free SO2 from the petroleum sulfonic acid prior to preparing the additive. Lubricating oil compositions containing these ashless additives are also provided.
