The invention relates to porphyrins, porphyrazines and phthalocyanines carrying a guanidine substituent. These compounds are obtained by treating a porphyrin, porphyrazine or phthalocyanine, respectively, carrying an amino substituent with cyanamide or a carbodiimide in an ionic liquid at elevated temperature. Described are valuable diagnostic, photoelectronic, and therapeutic uses, e.g. as photosensitizing agents in photodynamic therapy, fluorescent and magnetic probes for diagnosis, or to transport other molecules through the plasma membranes of living cells. Furthermore, the present invention relates to a method of removing a metal from metalloporphyrins, metalloporphyrazines and metallophthalocyanines by heating the zinc(II)-containing compounds in an ionic liquid and a proton source at temperatures between 60°C and 200°C.
