Fast-response light-emitting electrochemical cells based on neutral iridium(III) complex
چکیده انگلیسی

In this study, light-emitting electrochemical cells (LECs) based on neutral iridium(III) bis(2-phenylquinolato-N,C2′)(3-isoquinaldate) were fabricated. An admixed solid supporting electrolyte tetra-n-butylammonium tetrafluoroborate (TBABF4) is employed in the emitting layer, and it facilitates charge injection with decreasing the potential barrier under a biased voltage. The cells generate an electroluminescence (EL) of 300 cd m-2 at − 3.8 V. When the molar ratio of TBABF4 to the complex in the device was 2:1, a fast EL response of 0.8 s was obtained at − 4.0 V after the several times of preconditioning. As the quantity of the supporting electrolyte increased, a faster and brighter EL response was obtained.
