DOI: https://doi.org/10.1002/cptc.2017001762367-0932http://hdl.handle.net/10272/16177The excited-state behavior of four-coordinate N,C-chelate organoboron dyes, based on arylisoquinoline ligands with varying degree of charge-transfer character, was characterized. Data related to excited triplet state formation, oxygen quenching, and singlet-oxygen formation were obtained. The results jointly rationalize the previously observed high photostability of the dyes in air-equilibrated media. Furthermore, femtosecond transient absorption experiments enabled the spectroscopic visualization of the excited intramolecular charge transfer (ICT) state that gives rise to the fluorescence of the dyes.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Charge transferFluorescenceOrganoboron dyesPhotophysicsSinglet oxygenjournal article10.1002/cptc.201700176open access
