PURPOSE: A pyrene derivative compound is provided to provide an organic electroluminescence device operable at low voltage and having improved luminous efficiency by having stable and excellent luminous properties. CONSTITUTION: A pyrene derivative compound is represented by chemical formula 1-5. An organic electroluminescence device comprises an anode, a cathode, an electroluminescent layer comprising the compound and inserted between the anode and the cathode. Between the anode and the cathode, one or more layers selected from a hole injection layer, a hole transport layer, an electron block layer, a hole block layer, an electron transport layer and an electron injection layer. The one or more layers are formed by a monomer evaporation method of a solution process.

In this experiment, a series of thermal reactions of 4,4′- disubstituted 2,2′-bis(phenylethynyl)biphenyls with 2,3,4,5- tetraphenylcyclopenta-2,4-dienone were carried out under neat conditions and in diphenyl ether at temperatures between 260 and 270 °C t

2,2'-Diiodobiphenyl and 5,5'-dinitro-2,2'-dihalobiphenyls underwent palladium-catalyzed phenylethynylation with 2 mol of phenylacetylene to yield 3-(fluoren-9-ylidene)-1,3-diphenylpropyne and 3-(3,6-dinitrofluoren-9-ylidene)-1,3-diphenylpropyne, respectively.These fluorenyl compounds exhibited well-defined splitting patterns for the fluorenyl ring protons in the 250-MHz proton NMR spectra.The structure of 3-(fluoren-9-ylidene)-1,3-diphenylpropyne was further confirmed by an independent synthesis via the thermolysis of diethyl 3-(fluoren-9-ylidene)-1,3-diphenylpropen-1-yl phosphate.The mechanistic importance of the complex iodo(fluoren-9-ylidenebenzyl)bis(triphenylphosphine)palladium(II) in the catalytic cycle was established on the basis of its reaction with phenylacetylene to give 3-(fluoren-9-ylidene)-1,3-diphenylpropyne.
