Synthesis and Properties of Manganese(III) Complex of Salen-Analog Containing Phenolic Pendant Group
The electron affinities (EAs) of a training set of 19 metal-salen compounds were calculated using density functional theory. Concurrently, the experimental reduction potentials for the training set were measured using cyclic voltammetry. The EAs and reduction potentials were found to be linearly correlated by metal. The reduction potentials of a test set of 14 different metal-salens were then m...
(R)-1,2-Diaminobicyclo[2.2.2]octane was used as a starting material for the preparation, in solution or ball mill, of salen ligand. Five metal complexes were prepared high yield and their cytotoxic activities evaluated against Human Colon cancer HCT116 cell lines. The original manganese complex displayed highest activity with potency 16 fold higher than that cisplatin, demonstrating benefit bri...
Two new small-molecule enzyme mimics of carbonic anhydrase were prepared and characterized. These complexes contain the salen-like ligand bis(hydroxyphenyl)phenanthroline. This ligand is similar to the salen-type ligands previously incorporated into carbonic anhydrase mimics but contains no hydrolyzable imine groups and therefore serves as a promising ligand scaffold for the synthesis of a more...
Two new one-component aluminium-based catalysts for the reaction between epoxides and carbon dioxide have been prepared. The catalysts are composed of aluminium-salen chloride complexes with trialkylammonium groups directly attached to the aromatic rings of the salen ligand. With terminal epoxides, the catalysts induced the formation of cyclic carbonates under mild reaction conditions (25-35 °C...
The synthesis of statistical fluorene-type copolymers with on-chain Pt-salen phosphorescent units and their use in electrophosphorescent OLEDs is reported.
