A unimolecular ion channel was optimized by functionalization with a new type of rigid-rod oligomer. The macrocycle pendant endows chloride selectivity and the fluorescence feature and suitable length of the rod facilitates the visual insertion of channels into the lipid bilayer, resulting in efficient ion transport with an EC50 value of 0.36 μM.
Supporting multiple organometallic catalysts on poly(norbornene) for cyanide addition to α,β-unsaturated imides

A two-catalyst system comprising of salen(AlCl) and pybox(ErCl3) complexes supported onto poly(norbornene) has been developed. As a proof of concept the activity of the two-catalyst system was gauged for the addition of cyanide to α,β-unsaturated imides which has been shown to follow a bimetallic mechanism. The activity of the supported two-catalyst system was significantly higher than catalytic systems derived from mixtures of the two catalysts. In addition, the co-polymer could be readily recovered and reused up to 3 cycles without significant loss in conversions and yields. Nevertheless, a decrease in enantioselectivity of the cyanide adduct was observed with each subsequent cycle indicating some loss in catalytic selectivity. The reported strategy opens up avenues for supporting multiple catalysts on the same polymer backbone for catalyst-based one-pot cascade reactions.

A versatile one-pot synthetic platform for the preparation of a range of functionalized 2,6-bisbenzimidazolylpyridine (Bip) derivatives is presented. This protocol significantly reduces the cost and time of previous synthetic routes, while facilitating sc
Double versus single helical structures of oligopyridine-dicarboxamide strands. Part 2: The role of side chains
Haldar, Debasish,Jiang, Hua,Léger, Jean-Michel,Huc, Ivan
, p. 6322 - 6330 (2008/02/05)
A series of heptameric oligoamides comprising 4-alkoxy-substituted 2,6-diaminopyridine and 2,6-pyridine-dicarbonyl units have been synthesized using convergent methods. The hybridization of these compounds into double helical dimers was studied in solutio
Dendronized molecular knots: Selective synthesis of various generations, enantiomer separation, circular dichroism
Recker, Janosch,Mueller, Walter M.,Mueller, Ute,Kubota, Takateru,Okamoto, Yoshio,Nieger, Martin,Voegtle, Fritz
, p. 4434 - 4442 (2007/10/03)
For the first time, knot molecules (of the amide type) are synthesized, which bear one to three dendritic units of various generations at their periphery. They were obtained through two different routes: i) attachment of dendritic wedges to new mono-, di-
Novel synthesis of substituted 4′-hydroxy-2,2′:6′,2″-terpyridines

, p. 2263 - 2264 (2007/10/03)
4-Substituted-2,6-diacetylpyridines 2-4 have been synthesised; by using the Kroehnke-methodology, chalcone and methylacylpyridinium salts have been reacted to yield 4′-ethoxy-2,2′:6′,2″-terpyridines 5-7. These novel 2,2′:6′,2″-terpyridines are functionali
