Abstract :
8-Hydoxyquinoline (q) and 2-(2-hydroxyphenyl) benzoxazole (HPB) were employed as organic ligands and the corresponding organomatallic diphenyltin (IV) complexes (SnDP(HPB)2, SnDPQ2) were synthesized. And their electroluminescence (EL) properties were investigated. The structures of organotin (IV) complexes were determined by FT-NMR, FT-IR, UV-Vis and elemental analysis. The photoluminescence (PL) of organotin complexes was measured from the benzene solution. The PL emission exhibited light centered at about 440 and 515 nm. The devices with structure of ITO/NPB/organotin(IV) complexes /Alq3/LiF/Al were constructed to investigate their EL properties. The EL device using SnDPQ2 as the emitting layer showed green luminescence with a maximum emission peak at 535 nm. Complexes SnDP(HPB)2 and SnDPQ2 form a new family of organometallic emitting materials which could be of interest for practical applications.
