As part of our interest in chemistry of cationic boron compounds as anion receptors, we have synthesized 2-(4'-dimestylborylphenyl)-N-methyl-pyridinium triflate ([3]OTf) and 2-(5'-dimesitylborylthiophen-2-yl)-N-methyl-pyridinium triflate ([4]OTf) by reaction of the corresponding pyridyl derivatives with MeOTf. Both [3]OTf and [4]OTf extract fluorideions biphasically (H2O/CHCl3) to form the zwitterionic

tuned from red to near-infrared. All of the iridium(III) complexes were utilized in the fabrication of phosphorescent organic light-emitting diodes and their device performances were investigated. These electrophosphors emit in the red to near-infrared regions. The present work enables the rational design of new borylated iridium phosphors by synthetically tailoring the structure of oligothiophene-based
