Biomimetic models for redox enzyme systems
… that take place between molecules. A supramolecule or host-guest complex is formed when a noncovalent binding or complexation event occurs between two such molecules. Hydrogen bonds, electrostatics, pi-stacking, hydrophobic effects, solvatophobic effects and van der Waals forces are …

Labile Ligand Variation in Polyazine-Bridged Ruthenium/Rhodium Supramolecular Complexes Providing New Insight into Solar Hydrogen Production from Water
… (X = Br- or Cl-). The synthesis of a halide-free supramolecule containing OH- ligands afforded an ideal system to further examine the impact of the ligands at the reactive metal center on H2 photocatalysis. Electrochemistry results revealed that while the identity of the ligands at Rh did modulate …

Synthesis and Study of Polyazine Bridged Mixed Metal Dyads: Electrochemical, Photophysical, and Photochemical Properties of a New Supramolecular Architecture
… a polyazine bridging ligand. A related class of supramolecule is known to perform photoinitiated electron collection, photocatalysis of hydrogen from water, DNA photomodification and is known to kill mammalian cells; all with visible light irradiation. The complexes studied herein, …

Characterization of Cucurbituril Complex Ions in the Gas Phase Using Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
… universal for the investigation of all types of supramolecules, and usually they have one or more limiting factors such as relatively large sample consumption, matrix effects from solvents, etc. Electrospray mass spectrometry has been widely used to investigate host-guest interactions in the gas …

Modification of Excited State Behavior with Ligand Substitution in Ru(II),Rh(III) Bimetallic Supramolecular Complexes
The terminal ligand in [(Ph₂phen)₂Ru(dpp)RhCl₂(TL)](PF₆)₃ (Ph2phen = 4,7-diphenyl1,10-phenanthroline; dpp = 2,3-bis(2-pyridyl)pyrazine; TL = terminal ligand – a 4,4′-disubstituted-2,2′-bipyridine where the substituent was carbomethoxy (dcmbpy), hydrogen (bpy) or methyl (Me₂bpy)). The …

Supramolecular Approaches to Viscoelastic Biomaterials and Their Applications
Viscoelasticity encompasses the characteristics of both the shape-conserving elasticity and the shock-absorbing viscosity. The extracellular matrices (ECM), or the protein-polymer scaffolds surrounding the cells in our body, possess unique tissue-dependent viscoelasticity to protect and provide …
