B,B-diporphyrinbenzyloxy-BODIPY dyes: Synthesis and antenna effect

B,B-Diporphyrinbenzyloxy-BODIPY derivatives have been prepared in high yields, and the photophysical properties are reported. Singlet energy transfers from BODIPY to the porphyrin units have been analyzed.

Singlet and triplet energy transfer rate acceleration by additions of clusters in supramolecular pigment-organometallic cluster assemblies

Both S1 and T1 energy transfer rates (porphyrin → cluster) increase from mono- to di- to tetracarboxylate[tetraphenyl- (zinc)porphyrin] adducts with [Pd3(dppm)3(CO)] 2+ clusters.

Spectroscopic characterization of an assembled pair of free-base and zinc porphyrins linked by the cyclic β-sheet peptide Gramicidin S

A pair of porphyrins was linked to the Orn side chains of Gramicidin S [cyclo(-D-Phe-Pro-Val-Orn-Leu-)2] and its derivatives via the amide bonds; the assorted porphyrins were characterized by various spectroscopic methods. The high-field shifts of the porphyrin signals in the 1H NMR spectrum and the exciton-coupled Cotton effects in the CD spectrum of cyclo[-D-Phe-Pro-Val-Orn(Por)-Leu-]2 are both intense compared to those of cyclo[-D-Phe-Pro-Val-Dab(Por)-Leu-]2 or cyclo[-D-Phe-Pro- Val-Lys(Por)-Leu-]2 (Dab, diaminobutyric acid; Por, the side-chain linked porphyrin). Some 1H NMR signals of the tolyl protons of the porphyrins coalesce at 353 K in CD2Cl2, which reveals dynamic processes of the porphyrins. The intensities of the Cotton effect are: Gramicidin S with a pair of free-base porphyrins ≈ Gramicidin S with a free-base porphyrin and a zinc porphyrin 1H NMR, UV-vis, CD and fluorescence spectra show that the solvent substantially influences the assembly of the porphyrins. These spectroscopic studies suggest that the strength of the intramolecular interactions between a pair of porphyrins is in the order of toluene > CH2Cl2 > DMF.
