Microwave-Assisted synthesis of fluorine substituted porphyrins and kinetics of formation of zinc porphyrin complexes in acetic acid

Three mono-fluorine substituted porphyrin compouds were synthesized under microwave irradiation. The effects of catalysts and oxidants on the yields of mono-fluorine substituted porphyrins also were investigated. The yields of 5,10,15,20-tetrakis(4-fluoro

A four-phenyl porphine preparation method

The invention discloses a preparation method of meso-tetraphenylchlorin. The preparation method comprises the steps that 1, a mixed solution of pyrrole and aromatic aldehyde is prepared for standby; 2, a solvent is added into a polymerization reactor, nitrogen displacement is conducted till the concentration of tail oxygen is lower than 1%, the solvent is heated to backflow, the mixed solution obtained in the first step starts to be dropwise added, a reaction is started, after the mixed solution is dropwise added completely, the reaction is continuously conducted for 0.05 h to 0.5 h, and then the reaction is stopped; 3, oxygen-containing gas with the oxygen volume fraction ranging from 5% to 100% is fed into the polymerization reactor for oxidation, cooling is conducted after the oxidation is completed, filtration is conducted to obtain a filter cake and filtrate, and a product is obtained after the filter cake is washed and dried. The preparation method of the meso-tetraphenylchlorin has the advantages that the yield is high, safety and environmental protection are achieved, separation and purification are easy, and the product quality is stable.

Temperature-responsive Catalyst for the Coupling Reaction of Carbon Dioxide and Propylene Oxide

The selective synthesis of polypropylene carbonate (PPC) and cyclic propylene carbonate (CPC) from coupling reaction of CO2 and propylene oxide (PO) is a long term pursuing target. Here we report that a temperature controllable porphyrin alumin

Iron-based metalloporphyrins as efficient catalysts for aerobic oxidation of biomass derived furfural into maleic acid

A series of porphyrin type catalysts with the metal active sites of Fe were prepared and investigated in aerobic oxidation of biomass-based furfural to maleic acid (MAD) in aqueous phase. The catalytic performance of meso-tetrakis(4-bromophenyl)porphyrin iron (III) chloride (FeT(p-Br)PPCl) immobilized on different supports was evaluated. It was interesting to find that the catalytic activity varied with the supports and followed the trend: FeT(p-Br)PPCl/SBA–15 > FeT(p-Br)PPCl/meso-ZSM–5 > FeT(p-Br)PPCl/MCM-41. The effect of reaction conditions were discussed in detail over FeT(p-Br)PPCl/SBA-15 catalyst, and 56.1% yield and 73.8% selectivity of MAD were obtained from renewable furfural under the optimal conditions. Moreover, the FeT(p-Br)PPCl/SBA-15 catalyst could be reused five times without a significant decrease of activity in recycling examinations.

Amphiphilic meso(sulfonate ester fluoroaryl)porphyrins: Refining the substituents of porphyrin derivatives for phototherapy and diagnostics

A set of amphiphilic fluorinated porphyrins appended with sulfonate ester groups were synthesized and fully characterized. The reaction proceeds efficiently, with high yields, with an improved methodology. Their potential use as imaging and phototherapeutic agents was assessed measuring relevant photophysical properties. It is shown that these porphyrins have good photostability, long triplet lifetimes (between 47 μs and 102 μs), high singlet oxygen quantum yields (0.74≤FD≤1.00), low fluorescence quantum yields (0.04) and sharp 19F NMR peaks. The data on the new meso(sulfonate ester fluoroaryl)porphyrins illustrate the potential of perfluorinated sulfonate esters to improve physical properties relevant for cancer imaging and photodynamic therapy.
