Abstract:
An arginine-substituted zinc phthalocyanine (ArgZnPc) capable of disaggregating at high concentrations in polar non-aqueous solvents through concentration-driven hydrogen bond type transformation has been prepared. The ArgZnPc was prepared through a guanidine-meditated self-catalytic ester hydrolysis reaction. The concentration-driven disaggregation of ArgZnPc was confirmed by UV-Vis absorption spectra, fluorescence emission spectra and lifetimes, and singlet oxygen quantum yield data.
