Spectral Characterization of CPPs. (a) Normalized UV−vis absorption (dashed line) and fluorescence emission spectra (solid line) of 10–6 M CPP, CPP-pyrene, CPP-TPE, and CPP-COOH in THF. The fluorescence emission spectra were obtained by exciting the samples at = 340 nm. (b) Normalized color plots of the concentration-dependent fluorescence excitation spectra of CPP between 10–3 M and 10–6 M in THF ( = 540 nm).
