We describe the synthesis of a polycatenated cyclic polymer, a structure that resembles a molecular charm bracelet. Ruthenium-catalyzed ring-opening metathesis polymerization of an aminocontaining cyclic olefin monomer in the presence of a chain transfer agent generated an alpha,omega-diazide functionalized polyamine. Cyclization of the resulting linear polyamine using pseudo-high-dilution coppercatalyzed click cyclization produced a cyclic polymer in 19% yield. The click reaction was then further employed to remove linear contaminants from the cyclic polymer using azide- and alkyne-functionalized scavenging resins, and the purified cyclic polymer product was characterized by gel permeation chromatography, 1H NMR spectroscopy, and IR spectroscopy. Polymer hydrogenation and conversion to the corresponding polyammonium species enabled coordination and interlocking of diolefin polyether fragments around the cyclic polymer backbone using ruthenium-catalyzed ring-closing olefin metathesis to afford a molecular charm bracelet structure. This charm bracelet complex was characterized by 1H NMR spectroscopy, and the catenated nature of the small rings was confirmed using two-dimensional diffusionordered NMR spectroscopy.

An efficient method for the oxidation of benzylic and secondary aromatic alcohols into their corresponding aldehydes or ketones has been achieved by using ruthenium supported magnesium-lanthanum mixed oxide as a heterogeneous catalyst in toluene, with molecular oxygen as the sole oxidant. This catalyst can also be operated in solvent free conditions at 393 K and reused for five cycles with consistent yield and selectivity.

A set of molecular triads was synthesized in which terminal ruthenium(II) and osmium (II) tris(2,2′-bipyridyl) fragments were separated by a butadiynylene residue bearing a central aromatic nucleus. The aromatic groups (1,4-phenylene, 1,4-naphthalene, and 9,10-anthracene) significantly influenced the nature of intramolecular triplet energy-transfer processes involving the terminals. Electron exchange occurred via superexchange interactions with the central phenylene group acting as mediator. The triplet energy of the connector decreased after replacing phenylene with naphthalene, such that the naphthalene-like triplet lies at slightly lower energy than the Ru(bpy) fragment but higher than the triplet state localized on the Os(bpy) unit. Triplet energy transfer along molecular axis entailed two discrete steps, forming the naphthalene-like triplet as a real intermediate, both of which were fast. The triplet energy of the anthracene-derived connector, which was lower than that of the Os(bpy) fragment, acted as an energy sink for photons absorbed by the terminal metal complexes. There was a slow energy leakage from the anthracene-like triplet to the Os(bpy) unit, which stabilized the latter triplet state, and provided a way for obtaining energy transfer along the molecular axis.

The new dye complex bis[4,4?-di(2-(3-methoxyphenyl)ethenyl)-2, 2?-bipyridine][4,4?-dicarboxy-2,2?-bipyridine]-ruthenium(II) dihexafluorophosphate (1) has been prepared, characterised by absorption spectroscopy and adsorbed onto nanocrystalline TiO2 electrodes. The resulting system was studied by absorption spectroscopy, electrochemistry and photoelectrochemistry and the results were compared to those for a reference system with bis[2,2?-bipyridine]-[4,4?-dicarboxy-2,2?- bipyridine]ruthenium(II) (2). The system with 1 displays a broader and red-shifted UV-vis absorption compared to that with 2. Moreover, the system with 1 is less sensitive towards the water content in the electrolyte, and an adsorbed monolayer of 1 remains on the electrode surface after days even in aqueous NaOH (0.1 M), while 2 desorbs immediately.

Dinuclear dichloro complexes [Ru(C6H6)Cl 2]2, [Ru(p-MeC6H4 iPr)Cl2]2, [Ru(1,2,4,5-C6H 2Me4)Cl2]2, and [Ru(C 6Me6)Cl2]2 react in ethanol with p-bromothiophenol to give the corresponding cationic complexes [Ru 2(C6H6)2(p-S-C6H 4-Br)3]+ (1), [Ru2(p-MeC 6H4iPr)2(p-S-C6H 4-Br)3]+ (2), [Ru2(1,2,4,5-C 6H2Me4)2(p-S-C6H 4-Br)3]+ (3), and [Ru2(C 6Me6)2(p-S-C6H4-Br) 3]+ (4), which can be isolated in quantitative yield as their chloride salts. X-ray structure analysis of these complexes shows that the nature of the arene ligand influences the folding of the p-S-C 6H4-Br units. In 1, where the less hindered arene ligand is present, the three phenyl rings of the thiolato units are not constrained to a coplanar arrangement, whereas in 4 the C6Me6 forces the three phenyl rings to be in perfect planarity. Complexes 2 and 3 show an intermediary arrangement.

(Chemical Equation Presented) Lock it in: A temporary silicon-based configurational lock (see scheme) has enabled an efficient and fully diastereo-selective assembly of the spiroketal subunit of spirofungin A. This complex natural product was synthesized in 20 steps, including a rapid polyketide assembly based on the ring-opening metathesis of a cyclopropenone acetal. It was established that spirofungin A elicited notable anti-proliferative activity against several human cancer cell lines and selectively inhibited isoleucyl-tRNA synthetase in vitro.

Carbohydrates are integral to biological signaling networks and cell-cell interactions, yet the detection of discrete carbohydrate-lectin interactions remains difficult since binding is generally weak. A strategy to overcome this problem is to create multivalent sensors, where the avidity rather than the affinity of the interaction is important. Here we describe the development of a series of multivalent sensors that self-assemble via hydrophobic supramolecular interactions. The multivalent sensors are comprised of a fluorescent ruthenium(II) core surrounded by a heptamannosylated beta-cyclodextrin scaffold. Two additional series of complexes were synthesized as proof-of-principle for supramolecular self-assembly, the fluorescent core alone and the core plus beta-cyclodextrin. Spectroscopic analyses confirmed that the three mannosylated sensors displayed 14, 28, and 42 sugar units, respectively. Each complex adopted original and unique spatial arrangements. The sensors were used to investigate the influence of carbohydrate spatial arrangement and clustering on the mechanistic and qualitative properties of lectin binding. Simple visualization of binding between a fluorescent, multivalent mannose complex and the Escherichia coli strain ORN178 that possesses mannose-specific receptor sites illustrates the potential for these complexes as biosensors.
