Meso-substituted borondipyrromethene (BODIPY)-porphyrin compounds that include free base porphyrin with two different numbers of BODIPY groups (BDP-TTP and 3BDP-TTP) were designed synthesized to analyze intramolecular energy transfer mechanisms meso-substituted BODIPY-porphyrin dyads the effect connected free-base on mechanism. Absorption spectra conjugates showed wide absorption features in vi...

Highly fluorescent and thermo-stable peptide nanoribbons (PNRs) were fabricated by solvothermal self-assembly of a single peptide (D,D-diphenyl alanine peptides) with Sn-porphyrin (trans-dihydroxo[5,10,15,20-tetrakis(p-tolyl)porphyrinato] Sn(IV) (SnTTP(OH)2)). The structural characterization of the as-prepared nanoribbons was performed by transmitting electron microscopy (TEM), scanning electro...

A new dissymmetrically disubstituted diiron dithiolate species, [Fe(2)(CO)(4)(κ(2)-P(Ph)(2)N(Ph)(2))(μ-pdt)] (pdt = S(CH(2))(3)S), was prepared by using a flexible cyclic base-containing diphosphine, 1,3,5,7-tetraphenyl 1,5-diaza-3,7-diphosphacyclooctane (P(Ph)(2)N(Ph)(2) = {PhPCH(2)NPh}(2)). Preliminary investigations of proton and electron transfers on the diiron system have been done.

Free porphyrins are formed by growing cultures of some bacteria and yeasts under conditions in which formation of cytochromes is limited. With Corynebacterium diphtheriae, production of both porphyrin and toxin is dependent upon the concentration of iron salts in the medium; increasing this beyond a critical point decreases both porphyrin and toxin production (Pappenheimer, 1947). Cells grown w...

In order to shed more light on the effect of peripheral groups of porphyrin core intophysicochemical properties and DNA binding behavior of porphyrins, we have chosen toinvestigate solution properties and calf thymus DNA binding behavior of meso-tetrakis (4-Nbenzyl-pyridyl) porphyrin (TBZPyP) and its Mn (III), Co (III), Ni (II) and Cu (II) complexesderivatives have been studied in thermodynamic...

The comparative study of the spectral-luminescent properties hydrophilic 21-thia-5,10,15,20-tetra-(4-sulfonatophenyl)-porphyrin and 5,10,15,20-tetra-(4-sulfonatophenyl)-porphyrin is carried out in solutions at 293 K. peculiarities halochromic effects have been revealed for first time, which were due to replacement pyrrole ring by thiophene macrocycle. It found that multicenter interactions&#x0D...
