Their photophysical properties in solution and in the solid state have been analyzed and three main practical results have been obtained: (i) a dual fluorescent and phosphorescent emissive complex in solution, (ii) successful acid/base sensing in the solid state and (iii) quantitative CO2 detection. Quantum chemical calculations have been employed to assign the character of the lowest excited states. A plausible explanation for the observed aggregation induced enhanced emission (AIEE) is given, based on the restriction of intramolecular motions due to the effect of intermolecular C-Hp and C-HCl type interactions upon aggregation.15 p.application/pdfengcc by (c) Climent Biescas, Claudia et al., 2017http://creativecommons.org/licenses/by/3.0/es/IridiLligandsAgregació (Química)SolubilitatIridiumLigandsAggregation (Chemistry)Solubilityinfo:eu-repo/semantics/article6836372018-12-20info:eu-repo/semantics/openAccess
