Design and Modification of Polyazine-Bridged Ru(II),Rh(III) Bimetallic and Trimetallic Supramolecular Complexes Applicable in Solar Energy Harvesting for the Photocatalytic Reduction of Water to Hydrogen
… and Rh(dσ*) orbitals make electronic tuning with steric protection of the photogenerated Rh(I) difficult. Within [(TL)₂Ru(dpp)RhCl₂(TL′)]³⁺ bimetallics (TL = Ph₂phen or bpy; TL′ = Ph₂phen or tBu₂bpy), a careful balance of steric and electronic effects was required to produce active photocatalysts. …

The Design, Synthesis and Study of Mixed-Metal Ru,Rh and Os, Rh Complexes with Biologically Relevant Reactivity
… for analogous Ru,Rh,Ru trimetallics due to the steric protection of the Rh site in that motif. The bimetallic [(TL)2Ru(dpp)RhCl2(TL)]3+ systems can photobind and photocleave DNA through low-lying 3MMCT excited states when excited by the low energy visible light, with or without molecular oxygen. …

Investigations into cyclopropanation and ethylene polymerization via salicylaldiminato copper (II) complexes
… test reaction for homogeneous catalysts. Sterically bulky salicylaldimine (SAL) ligands should select for the ethyl trans-2-phenylcyclopropanecarboxylate diastereomer. Steric bulk poorly influences trans:cis ratios. Salicylaldiminine ligands do not posses the correct symmetry to affect …
