Hexaporphyrin- and hexathiaporphyrin-substituted cyclotriphosphazenes are prepared as well as the zinc and copper complexes of a hexaporphyrin-substituted cyclotriphosphazene. Reaction of hexachlorocyclotriphosphazene with six equivalent of a hydroxyphenyl-substituted porphyrin or thiaporphyrin in THF with cesium carbonate as a base yields hexaporphyrin-substituted and hexathiaporphyrin-substituted cyclotriphosphazenes in 85% and 87% yields, resp.; treatment of the hexaporphyrin-substituted cyclotriphosphazene with either zinc acetate or copper (II) chloride under standard metalation conditions yields the corresponding zinc and copper hexaporphyrin-substituted cyclotriphosphazene complexes. The UV/visible spectra of monomeric porphyrins and thiaporphyrins, the hexaporphyrin- and hexathiaporphyrin-substituted cyclotriphosphazenes, and the zinc and copper hexaporphyrin-substituted cyclotriphosphazene complexes are obtained. The absorption spectra and calculated conformations of the hexaporphyrin-substituted cyclotriphosphazene are determined; the compound forms ringlike structures observed by fluorescence microscopy. The oxidation and reduction potentials of the hexaporphyrin- and hexathiaporphyrin-substituted cyclotriphosphazenes, and the zinc hexaporphyrin-substituted cyclotriphosphazene complex are determined Copper hexaporphyrin-substituted cyclotriphosphazene complex cleaves supercoiled DNA in the absence of added oxidant; neither the hexaporphyrin-substituted cyclotriphosphazene nor copper tetraphenylporphyrin cleave supercoiled DNA under analogous conditions. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Recommanded Product: 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Ligand, in chemistry, any atom or molecule attached to a central atom, usually a metallic element, in a coordination or complex compound. Precious metals and metal oxides on carrier materials are used in many industrial processes as heterogenous catalysts.Recommanded Product: 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol
