Trimer Porphyrin Star

Abstract

A novel tripod star-shaped porphyrin trimer has been synthesized using "click" methodology (Huisgen's 1,3-diploar cycloaddition reaction) from zinc 15,3,

New Pegylated Unsymmetrical meso-Arylporphyrins as Potential Photosensitizers

“…Heightened interest to the synthesis of unsymmetrically substituted amphiphilic porphyrins is due to their use in PDT, supramolecular chemistry, [10] biomimetic systems, [11,12] nonlinear optics. [13] As it was noted above, the modification of hydroxyphenyl porphyrins by oligo-and polyethylene glycol residues greatly increases their solubility in water and therefore expands biomedical scope of tetrapyrroles.…”

Metal Catalysis in the Transformations of Porphyrins

“…of meso-(4-ethynylphenyl)porphyrinate in the presence of CuI/DIPEA in THF-MeCN (Scheme 14) and it produced an isomeric porphyrin triad also in a high 70% yield. Porphyrin triad of a star shape [24] was obtained using the similar approach in which 1,3,5-tri-(ethynyl)benzene was reacted with 3 equiv. of meso-(4-azidophenyl) substituted porphyrinate.…”

Porphyrin-Containing Polymacrocycles: Synthesis and Evaluation as Fluorescent Detectors of Metal Cations

“…For this purpose Suzuki, [4][5][6] Stille, [7,8] Heck, [9] and Sonogashira [10,11] couplings were successfully applied. Triazolyl linker can be easily introduced in the porphyrin dyads and triads by еру so-called сlick reactions, [12][13][14] and the application of Buchwald-Hartwig amination reactions was reported for the synthesis of bisporphyrin compounds in which two macroheterocyles were linked with a simple NH fragment, [15] a series of di-an polyporphyrin compounds was obtained by a similar approach in which diamines or diazacrown ether moieties served as linkers. [16,17] While porphyrins possess extremely interesting photophysical properties together with their unique binding of metal cations, they have not yet become a widespread platform for creating colorimetric or fluorimetric chemosensors.…”
