Procedure

0.52 mmol (0.064 g) of picolinic acid was added to a room-temperature solution of 0.14 mmol 2-phenylbenzoxazole Iridium chloride dimer (0.18 g) in 20 mL of dichloromethane. The mixture was heated to reflux under nitrogen in an oil bath overnight (17.5 hrs.). Reaction mixture was cooled to room temperature, and the yellow precipitate was filtered off via vacuum. The precipitate was dissolved in dichloromethane and transferred to a vial, and the solvent was removed. Emission spectrum is in FIG. 46.
