Spectral features of conjugated bichromophores: porphyrins with curcumin

Conjugated bichromophores of porphyrins with natural compound curcumin were synthesized and studied by methods of spectroscopy. The fluorescence spectra of bichromophore consist of four bands covered almost a whole visible spectrum from 450 to 700 nm. A relatively weak interaction between curcumin and metalloporphyrin allows to combine both effects: high generation efficiency of singlet oxygen by metalloporphyrin and an anticancer treatment of curcumin

Creation of chemically conjugated multichromophoric complexes based on meso-substituted metalloporphyrins

New multichromophoric complexes based on metallocomplexes of meso-tetraphenylporphyrins chemically conjugated with curcumins and para-terphenyls have been synthesized. Four bands appeared in the luminescence spectrum were assigned. Two first bands in the spectrum at 465 and 497 nm correspond to the luminescence of curcumin, and the bands at 619 and 677 nm belong to the luminescence of the meso-substituted metallocomplex of porphyrin. Similar spectral data are manifested in the fluorescence spectra of a complex with four para-terphenyl substituents. For the last one compound the energy transfer between the molecules of the para-terphenyl and metalloporphyrin was postulated with the efficiency of about 20%
