AB The excited-state behavior of four-coordinate N,C-chelate organoborondyes, based on arylisoquinoline ligands with varyingdegree of charge-transfer character, was characterized. Datarelated to excited triplet state formation, oxygen quenching,and singlet-oxygen formation were obtained. The results jointlyrationalize the previously observed high photostability ofthe dyes in air-equilibrated media. Furthermore, femtosecondtransient absorption experiments enabled the spectroscopicvisualization of the excited intramolecular charge transfer (ICT)state that gives rise to the fluorescence of the dyes.
