(a) Differences in UV-Vis absorption and fluorescence emission spectra (inset, Ex: 636 nm) of 10 μM Pc4SNP and Pc4 in aqueous solution. (b) Fluorescence decays of 5 μM Pc4SNP and Pc4 in aqueous solution (Ex: 636 nm, Em: 680 nm). Both decays are fit to a single exponential function with a time constant of 5.21 ± 0.04 ns for Pc4SNP and 4.59 ± 0.03 ns for Pc4. The top set of residuals is for Pc4SNP; the bottom set, for Pc4.
