Abstract	The photophysical properties of seven luminescent iridium complexes are characterised in their single-crystal form and the photo-activity is related to their molecular structures. Specifically, solid-state optical emission spectra and associated lifetimes are determined from single crystals of iridium complexes containing three bidentate ligands: two variously substituted 2phenylbenzothiazoles and either a 2,4-pentadione (acetylacetone) or 2-pyridinecarboxylic (picolinic) acid. All complexes studied exhibit emissive behaviour in the solid-state which originates from * and metal-to-ligand-charge-transfer (MLCT) electronic transitions; this is supported by density functional theory. Phosphorescence is observed in all cases with microsecond lifetimes, ranging from 0.30-2.4 s at 298K and 1.4-4.0 μs at 100 K. Structureproperty relationships are established which are relevant to the potential solid-state application of this series of luminescent complexes as organic light emitting diodes (OLED) material components. In addition, these materials are assessed for their suitability to time-resolved pump-probe photocrystallography experiments, which will reveal their photo-excited-structure. Accordingly, the design process by which materials are selected, and technical parameters are defined, for a photocrystallography experiment is illustrated. This family of complexes presents a case study for this photocrystallography material profiling. Results show that the time-resolved photo-excited state structure, featuring the MLCT transition is, in principle at least, viable for two of these complexes.
