Fig. 2. (a) Normalized phosphorescence spectra of complexes 1 (blue) and 2 (red) in MeOH at 298 K. (b) Phosphorescence spectral traces of complex 1 (1.4 μM) in MeOH at 298 K in the presence of 0–50 μM NaClO. (c) Phosphorescence spectral traces of complex 2 (1.5 μM) in MeOH at 298 K in the presence of 0–50 μM NaClO. (d) Phosphorescence titration curves of complexes 1 (blue) and 2 (red). The excitation wavelength was 405 nm. The emission intensities of complexes 1 and 2 were monitored at 500 and 598 nm, respectively.
