12. The emission in the visible region-see for example earlier work by Sun et al.-exhibited no quenching when comparing 2a and 2b with matching absorbances at the excitation wavelength. Similarly, no changes were noted in the underlying radiative lifetime (approximately 3.0 ns).

16. Excitation of the 890 and 1300 nm fluorescence transitions led to rather poorly resolved spectra with a series of broad maxima. For example, for the emission maximum at 890 nm excitation maxima were found at 440 nm, 600 nm, and 790 nm.
17. The radiative decay constants were determined for both 2a and 2b by time-resolved fluorescence measurements. By following the emission up to 850 nm (i.e., the upper limit of our strobe detection system) we noticed that the lifetime, which in 2a is about 1.8 ns and agrees well with published data, is substantially shorter in 2b (major component of 0.2 ns).
18. Similar features were obtained on electrolysis of 2a (see Supporting Information). The spectroelectrochemical experiments were carried out in a quartz OTTLE cell with a 0.03 cm path length.
