Photoluminescence and electroluminescence of pyrazoline monomers and dimers
CHEMICAL JOURNAL OF CHINESE UNIVERSITIES-CHINESE(2000)
Abstract
The photo-lummescence behavior of seven kinds of pyrazoline monomer and dimer in solution and film has been studied comparatively in this work, The electro-luminescence properties of the material containing dopant in EL device, in which the structure [ITO/TPD/TPBI : EP/TPBI/Mg : Ag] was employed, have also been investigated. The results indicated that the EL devices composed of pyrazoline compounds showed itself a very good ability on the electro-luminescence, especially, of the pyrazoline compound in which a 5-position substitution existed. The devices obtained also showed itself a good stability due to their excellent film formation and high T-g transition temperature of the compounds used. The results demonstrated that the fluorescence quantum yields of mono-pyrazoline compounds in solution were higher than that of pyrazoline dimer, The identical tendency in the emission intensity has also been observed when the EL devices were composed of them.
