Photoreactions of 3-Tosyl- and 6-Tosyl-dihydro-1,3-diazaazulanones to Form 1,3-Diazaazulanones and Ionic Pairs between p-Toluenesulfonate Anion and 1,3-Diazadihydroazulanone Cations

A solvent effect was found on the photoreactions of 1-aryl-3-tosyldihydro-1,3-diazaazulanones with a low pressure mercury lamp. Thus, ion pairs between p-toluenesulfonate anion and the corresponding 1-aryl-1,3-diazadihydroazulanone cations were afforded by the reactions in THF. On the other hand, the corresponding 1-aryl-1,3-diazaazulanones were formed by the reactions in the other solvents. The analogous photoreactions with 1-aryl-6-tosyldihydro-1,3-diazaazulanones afforded the corresponding 1-aryl-1,3-diazaazulanones.

A specific nitrogen-containing heterocyclic compound having a urea structure, an electron transporting material containing the nitrogen-containing heterocyclic compound, and an organic electroluminescence device including a light emitting layer and an electron transporting layer between a cathode and an anode in which the electron transporting layer includes the electron transporting material or the nitrogen-containing heterocyclic derivative. An organic EL device exhibiting high emission efficiency even at low voltage and a material for organic EL devices are described.
