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.

A self-complementary heteroditopic molecule composed of thymine and diamidopyridine end groups and a flexible aliphatic interconnecting chain has been synthesized. The glassy dynamics of this hydrogen-bonded supramolecule have been investigated by using dielectric and rheological measurements, in combination with infra-red spectroscopy and solid-state 13C NMR experiments. Decoupling of main dielectric relaxation from viscosity has been found in the vicinity of the glass transition and the temperature dependence of viscosity appears to be stronger than that of dielectric relaxation. The unusual dynamic decoupling phenomenon is ascribed to the chemical/dynamic heterogeneity and formation of hydrogen bonds in the supramolecules.

, p. 1889 - 1898 (2007/10/03)
Split-and-mix libraries of resin-bound "tweezer" receptors have been prepared and screened to identify receptors for dye-labelled tripeptides. The receptors incorporate a diamidopyridine unit to serve as a specific recognition site for the CO2H
Identification of sequence-selective receptors for peptides with a carboxylic acid terminus
Fessmann, Thilo,Kilburn, Jeremy D.
, p. 1993 - 1996 (2007/10/03)
A combinatorial library of 'tweezer' receptors, which incorporate a diamidopyridine unit to provide a specific binding site for a CO2H group (see picture), can be screened to identify sequence-selective receptors for chosen peptide guests with

New crown compounds 3-5 comprising beside o-phenylelene groups 1,8-naphthyridine or 4-pyridone groups as characteristic building units are synthesized.They form numerous stoichiometric crystalline complexes with uncharged organic molecules including alcoh
Proton-Ionizable Crown Compounds. 2. Synthesis, Complexation Properties, and Structural Studies of Macrocyclic Polyether-Diester Ligands Containing a 4-Hydroxypyridine Subcyclic Unit

, p. 4865 - 4872 (2007/10/02)
A series of macrocyclic polyether-diester ligands containing a proton-ionizable 4-hydroxypyridine subcyclic unit has been prepared.These new macrocyclic ligands form stable complexes with both alkylammonium perchlorate salts and with alkylamines.The crystal structure for one of these complexes with an alkylamine shows that the hydroxy proton has been donated to the amine with the resultant formation of a 4-pyridone unit.Chiral dimethyl- and diphenyl-substituted macrocycles containing the 4-hydroxypyridine subcyclic unit exhibit chiral recognition for the enantiomers of 2-(1-naphthyl)ethylamine and their hydrogen perchlorate salts.
