Bioorthogonal control of the phosphorescence and singlet oxygen photosensitisation properties of iridium(III) tetrazine complexes.

In this work, we demonstrate bioorthogonal control of the phosphorescence and singlet oxygen photosensitisation properties of new iridium(iii) tetrazine complexes by different reaction partners; the system was exploited for organelle-specific staining and modulated photocytotoxic activity applications.
