Merging Supramolecular and Covalent Helical Polymers: Four Helices within a Single Scaffold

Supramolecular and covalent polymers share multiple structural effects such as chiral amplification, helical inversion, sergeants and soldiers, or majority rules, among others. These features are related to the axial helical structure found in both types

Conformationally constrained analogues of diacylglycerol (DAG). 27. Modulation of membrane translocation of protein kinase C (PKC) isozymes α and δ by diacylglycerol lactones (DAG-lactones) containing rigid-rod acyl groups

Highly rigid and geometrically well-defined rods composed of ethynylene-substituted aromatic spacers [oligo-(p-phenyleneethynylene), OPE] were incorporated as acyl moieties on diacylglycerol lactones (DAG-lactones) and investigated for their ability to bind to protein kinase C (PKC) and translocate PKC α and δ isoforms to plasma and internal membranes. The kinetics of PKC translocation were correlated with biological responses, viz. ERK phosphorylation, induction of IL-6 secretion, inhibition of cell proliferation, and induction of cellular attachment, that display very different time courses. Because OPE rods assemble through noncovalent forces and form stable films, they may influence the microdomain environment around the DAG-lactone membrane-binding site. A comparison of two DAG-lactones (1 and 10), one with two PE units (1) and the other with an equivalent flexible acyl chain (10) of matching lipophilicity, clearly demonstrated the effect of the rigid OPE chain in substantially prolonging the translocated state of both PKC α and δ.

Evidence for the assembly of carboxyphenylethynyl zinc porphyrins on nanocrystalline TiO2 surfaces

UV-visible absorption and AFM studies suggest that carboxyphenylethynyl zinc porphyrins aggregate on nanocrystalline TiO2 surfaces in an H-type fashion. The Royal Society of Chemistry 2006.

Delocalization of free electron density through phenylene-ethynylene: Structural changes studied by time-resolved infrared spectroscopy

We have studied the photochemistry of 1,4-bis(2-[4-tert-butylperoxycarbonylphenyl]ethynyl)benzene (1) and tert-butyl 4-(2-{4-[2-(4-phenyloxycarbonylphenyl)-1-ethynyl]phenyl}-1-ethynyl)peroxybenzoate (2). Excitation of 1 and 2 by a 355-nm laser pulse leads to the rapid formation of aroyloxyl radicals. An unpaired electron conjugated with the phenylene-ethynylene core is substantially delocalized over the π-system of the chromophore. The -C≡C- vibrational frequencies of these radicals are red-shifted relative to 1 and 2 as measured by time-resolved IR spectroscopy. This shift is attributed to the change in the triple bond character due to delocalization of the free electron. Copyright
