Meso-tetra (4-carboxyphenyl) porphyrin complexes with nano-sized diamonds were studied spectroscopically. The polarization characteristics of their steady-state fluorescence indicate the formation of a covalently bound complex between porphyrin molecules and diamond nanoparticles. The hydrodynamic volumes of the studied complexes were estimated on the basis of data on steady-state fluorescence anisotropy. Measurements have shown that the photophysical properties of porphyrin do not change significantly when an organo-inorganic hybrid complex with nanodiamonds is formed. The studied complexes can be promising in the field of biomedical research, in particular, for diagnostic purposes and for the development of new generation photosensitizers for practical medicine.
