The microspherical catalysts also proved to be recyclable with no drop in activity being observed after three successive reactions. The vanadium functionalized fibers were applied in a pseudo continuous flow set-up. Factors influencing the overall conversion and product selectivity, including flow rate and catalyst quantity, were investigated. At flow rates of 1–4 mL h−1 near quantitative conversion was maintained over an extended period. Keeping the mass of catalyst constant (0.025 g) and varying the flow rate from 1–6 mL h−1 resulted in a shift in the formation of the oxidation product methyl phenyl sulfone from 60.1 to 18.6%.]]> Wed 10 Apr 2024 14:17:42 SAST ]]> Synthesis and solvent effects on the photophysicochemical properties of novel cadmium phenoxy phthalocyanines https://commons.ru.ac.za/vital/access/manager/Repository/vital:54217 Wed 08 May 2024 17:27:36 SAST ]]> Photophysical study of a covalently linked quantum dot–low symmetry phthalocyanine conjugate https://commons.ru.ac.za/vital/access/manager/Repository/vital:53430 Wed 08 May 2024 16:26:28 SAST ]]> Photocatalytic behaviour of tantalum (V) phthalocyanines in the presence of gold nanoparticles towards the oxidation of cyclohexene https://commons.ru.ac.za/vital/access/manager/Repository/vital:51628 Wed 08 May 2024 16:19:45 SAST ]]> Unquenched fluorescence lifetime for β-phenylthio substituted zinc phthalocyanine upon conjugation to gold nanoparticles https://commons.ru.ac.za/vital/access/manager/Repository/vital:51404 Wed 08 May 2024 16:18:02 SAST ]]> Synthesis and photophysical behavior of a novel zinc phthalocyanine containing a single carboxylic acid and three phenylthio substituents https://commons.ru.ac.za/vital/access/manager/Repository/vital:51127 Wed 08 May 2024 16:16:20 SAST ]]> Oxovanadium (IV)-catalysed oxidation of dibenzothiophene and 4, 6-dimethyldibenzothiophene https://commons.ru.ac.za/vital/access/manager/Repository/vital:51429 Wed 08 May 2024 16:15:32 SAST ]]> The synthesis and characterisation of magnetic nanoparticles and their interaction with a zinc phthalocyanine https://commons.ru.ac.za/vital/access/manager/Repository/vital:51002 Wed 08 May 2024 16:15:04 SAST ]]> Effect of peripheral fused ring substitution on the optical spectroscopy and electronic structure of metal phthalocyanine complexes https://commons.ru.ac.za/vital/access/manager/Repository/vital:53620 Wed 08 May 2024 15:30:39 SAST ]]> Synthesis and photophysical properties of covalent conjugates of aqua platinum (II) and octacarboxy-substituted zinc phthalocyanine https://commons.ru.ac.za/vital/access/manager/Repository/vital:51073 Wed 08 May 2024 15:30:00 SAST ]]>
