New meso-tetra(benzo-12-crown-4)-substituted magnesium(II), aluminum(III), and gallium(III) porphinates are obtained. The structure of complexes is established using the data of electron absorption spectroscopy and MALDI TOF mass spectrometry. Comparative analysis of luminescent properties (energies of fluorescent transitions and fluorescence quantum efficiency) of metal porphyrinates and free meso-tetra(benzo-12-crown-4)-substituted porphyrin in a dimethylformamide solution at 25°C. It is found that the obtained metal porphyrinates are characterized by rather intense fluorescent radiation, as well as solubility in organic media of very different polarities, which allows considering new complexes as potential luminescent sensors for metal cations and as luminescent agents of metal cation interphase transfer.
