چکیده
The complex [Ru(bpy)2L] , where bpy = 2,2’-bipyridine, L = 4-(phenylethynyl)-2,2’-bipyridine, was prepared in its racemic and resolved forms (and . The phenylethynyl unit on the bipyridine for the complex acts as a binding site for -cyclodextrin in water (1:1 complex, K = 3390 M) or -cyclodextrin (2:1 complex, K1 = 887 M , K2 = 8070 M ). The presence of the cyclodextrin provides partial protection to the complex under light-activated water oxidation

Thermodynamic, spectral and antimicrobial activity of inclusion complexes of acridone and its oxime with β-cyclodextrin
One of the methods to enhance bio-accessibility of drugs like Acridone and its oxime is toform inclusion complexes with β-cyclodextrin. The formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. The aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. The studyof thermodynamic parameters like ΔG,...

The interaction of brilliant green with herring sperm DNA was investigated in detail by spectrometric methods in γ-cyclodextrin systems. On the condition of physiological pH, brilliant green prefers to form the 1:1 inclusion complex with γ-cyclodextrin.All the evidences indicated that the binding modes between γ-cyclode...
متن کاملSolid-phase synthesis of tris-heteroleptic ruthenium(II) complexes and application to acetylcholinesterase inhibition.
A synthetic route with two consecutive coordination chemistry steps on a solid support affords tris-heteroleptic ruthenium(II) polypyridyl complexes with high purity and in good yields. As an application we report the identification of a nanomolar acetylcholinesterase inhibitor from a small ruthenium complex library synthesized on Lanterns.
متن کاملPhotoinduced electron transfer between metal-coordinated cyclodextrin assemblies and viologens.
Two novel tris(bipyridine)ruthenium(II) complexes bearing two and six beta-cyclodextrin binding sites on their ligands have been synthesised and characterised. Complex 1, bearing two cyclodextrins, adopts a conformation in aqueous solution where parts of the aromatic ligands are self-included into the cyclodextrin moieties. This results in a loss of symmetry of the complex and gives rise to a m...
متن کاملConstruction of a photoactive supramolecular system based on a platinum(II) bis-acetylide building block incorporated into a ruthenium(II) polypyridyl complex.
A new ruthenium(ii) polypyridyl-platinum(ii) diethynyl triad containing 3-ethynylphenanthroline linked by platinum(ii) bis-tributylphosphine organometallics, Ru(ii)-Pt(ii)-Ru(ii), and platinum(ii) bis-ethynylphenanthroline complex has been prepared. The ruthenium(ii)-metal triads, Ru(ii)-M-Ru(ii) (M = Pt(ii) and Au(i)), showed typical MLCT absorption bands and a lowest energy pi-pi* absorption ...
