Two novel iridium(III) complexes (2-FSBT)2Ir(acac) and (4-FSBT)2Ir(acac) (2-FSBT, (E)-2-(2-fluorostyryl)benzo[d]thiazole; 4-FSBT, (E)-2-(4-fluorostyryl)benzo[d]thiazole; acac, acetylacetone) were synthesized and characterized by 1H NMR and mass spectrometry. The organic light emitting diodes based on these complexes with the structure of ITO/m-MTDATA(10 nm)/NPB(20 nm)/CBP:Ir-complex(X %, 30 nm)/BCP(10 nm)/Alq3(30 nm)/LiF(1 nm)/Al(100 nm) were fabricated. The device based on (2-FSBT)2Ir(acac) exhibited a maximum efficiency of 9.32 cd/A, a luminance of 8800 cd/cm2; and the device based on (4-FSBT)2Ir(acac) showed a maximum efficiency of 8.5 cd/A, a luminance of 6986 cd/cm2. The Commission International de L’Eclairage (CIE) coordinates (1931) of these complexes were (0.619, 0.381) and (0.621, 0.378), respectively.
