Abstract:
New ligands N- isopropy-l 2-pheny-l 1H-benzo im ida zole and N- isoprop-y-l 2-( 4- fluo ropheny l)-1H-benzo im idazo le w ere prepared, and the ir correspond ing cyc lom eta la ted comp lexes ( bi)2 Ir ( acac) and ( fb i) 2 Ir ( acac) ( acac= acety lacetone) we re synthesized by the reac tion of these tw o ligands w ith IrCl3 and acety lacetone. The structures of the com plex es we re characterized by 1H NMR and e lem en tal ana lyses. The UV-v is and pho to lum inescence ( PL) spec tra were dete rm ined, and the electrochem ical behav io rs o f the comp lexes w ere studied. The com plexes had strong pho tolum -i nescence in dich lo rome thane at 514 nm and 493 nm, respectively. The e lectro chem ica l study show ed that the energy gap be tw een the HOMO and LUMO w as en la rged by introducing fluor ine on the benzene ring ( 0??13 and 0?? 15 eV respective ly fo r tw o com plexes), wh ich w as in accordance w ith the blue sh ift o f the max imum em ission wave leng th
