An organic light emitting diode includes an anode, an emission layer disposed on the anode and including a host, a phosphorescent dopant represented by Chemical Formula 1 and a fluorescent dopant represented by Chemical Formula 2, and a cathode disposed on the emission layer formed by mixing the fluorescent dopant with the phosphorescent dopant including an acceptor at a specific site, thereby energy loss during an emission process can be minimized and energy transfer efficiency can be improved and an organic light emitting diode with excellent luminous efficiency and an organic light emitting display device having the same can be achieved.

Solid phase synthesis has been used to carry out intramolecular aromatichomolyticsubstitution with benzoimidazole precursors. The protocol attaches the radical precursors to the resins via the radical leaving groups (in the aromatichomolyticsubstitution). When the radical reactions are complete, the leaving group, unaltered starting material and reduced uncylised products remain attached to the

Six-membered photochemical cyclisations of 2-iodo-N-(2-arylethyl)imidazoles proceeded regioselectively in higher yields than the equivalent tin hydride-mediated reactions. The decrease in yield of cyclisation products, 5,6-dihydroimidazo[2,1-a]isoquinolines containing strongly deactivating substituents on the aryl ring confirmed the electrophilic nature of the sigma-imidazol-2-yl radicals. The seven-membered
