Abstract
Lightemitting electrochemical cells LECs are a promising type of electroluminescent device for display and lighting applications In this study LECs based on ionic iridium complexes utilizing a tetrazole based ancillary ligand were fabricated and their electrical properties were investigated Two new iridiumIII complexes with tetrazole based ancillary ligands namely Irppy2tetrazolePF6 complex 1 and Irdfppy2tetrazolePF6 complex 2 where ppy is 2phenylpyridine dfppy is 224difluorophenylpyridine tetrazole is 5bromo22methyl2Htetrazol5ylpyridine and PF6 is hexafluorophosphate have been synthesized and characterized These synthesized complexes were used for the fabrication of LEC devices LECs based on complex 1 result in orange light emission 576 nm with the Commission Internationale de l’Eclairage CIE coordinates of 045 049 while complex 2 emits green 518 nm electroluminescence with the CIE coordinates of 033 049 Our work suggests that the light emission of cationic iridium complexes can easily be tuned by the substituents on the cyclometalated ligandsThis work was supported by the Basic Science Research Program through the National Research Foundation NRF of Korea funded by the Ministry of Education Science and Technology NRF2013R1A1A4A03009795 and the BK 21 PLUS Center for Advanced Chemical Technology 21A20131800002 Republic of Korea
