Emission Studies of Transition-Metal Complexes of 2,2′-Dipyridylamine. 1. Bis Complexes of Rhodium(III) and Iridium(III)
Luminescence spectra, lifetimes, and polarization spectra have been measured for the + and + complexes (HDPA=2,2′-dipyridylamine).The complexes in acidic or neutral solution each show a broad, symmetric, and structurless red emission with microsecond lifetime assigned a dd* phosphorescence.In strong basic solution, the deprotonated complexes exhibit a blue asymmetric emission with a long tail overlapping the red-emission band.This blue emission shows no vibrational structure and has a lifetime on the order of microseconds.This emission is 0.35-mum-1 blue shifted with respect to the red emission and 0.56-mum-1 red shifted with respect to the phosphorescence of the ligand in strong basic solution.This emission can be assigned as charge-transfer dPi* emission analogous to that for the 2+ complex or as ligand-localized PiPi* emission.Such a dPi* emission from a Rh(III) complex would be unique.The emission polarization for the red dd* emission exhibits a nonzero slope across the band; moreover, the lifetime also varies with emission wavelength.This anomalous behavior is apparently intrinsic to dd* emission since similar data are obtained for dd* emission of the previously studied + complex.The origin of this unique behavior is not apparent but could have its origin in (1) solvent-induced barriers (distortions) in the emitting state and/or (2) intrinsic differences in vibrational relaxation rates with the emitting state.
