The iridium(III) complexes, one of the best phosphorescent heavy-metal, are well known for their rich photochemical and photophysical properties. This project shows the synthesis and characterization of 2 charged iridium(III) complexesby 1H NMR, 13CNMR and mass spectroscopy. Both complexes were designed with ester functional groups which were used as the amine sensor.The preliminary results show that the complexes show the blue shift with butylamine addition.This study could be a benefit system to detect many narcotic drugs in the future.
