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%. [ABSTRACT FROM AUTHOR] |
