(a) Fluorescence spectra of PIC micelles formed from WCS and TPE-(N-COOH)4 in aqueous solution with different ratio of [NH3+]/[COO-]. (b) Fluorescence spectra obtained for TPE-(N-COOH)4 aqueous solution and PIC micelles assembled from WCS and TPE-(N-COOH)4 at the [NH3+]/[COO-] molar ratio of 1.0. , nm. The TPE-(N-COOH)4 concentration was fixed at 1.0 g/L in all case. The emission intensities measured at various ratios were normalized to the initial intensity.
