Molecular folding of C60 acetylenic cyclophanes: pi-stacking of superimposed aromatic rings.
[structure: see text] The syntheses of two distinct families of phenylyne helical cyclophanes with potential for organic materials are described. The meta-bonded atropisomers afford interesting bowtie-like and butterfly-like conformers from a palladium(0), copper-mediated coupling sequence. Molecular modeling revealed the contrasting stereochemistry in these systems from differential molecular ...
متن کاملDinuclear platinum complexes containing planar aromatic ligands to enhance stacking interactions with proteins.
In an approach to design drugs with higher affinity for π-π stacking and electrostatic interactions with targeted biomolecules, complexes of the type [{cis-Pt(A)2 (L)}2 -μ-{trans-1,4-dach}](NO3 )4 ((A)2 =(NH3 )2 or ethylenediamine (en), L=quinoline (quin) or benzothiazole (bztz), dach=trans-1,4-diaminocyclohexane) were synthesized. The quinoline complex, [{cis-Pt(en)(quin)}2 -μ-(dach)](NO3 )4 (...
متن کاملRamadan fasting: Do we need more evidence?
Over a billion of Muslims fast worldwide during Ramadan each year. Through this religious custom, fasting contributes to their health as well as their spiritual growth. However, available evidence regarding the health-benefits of Ramadan fasting is scarce and highly contentious. Although Islam exempts patients from fasting, many fast conceivably, and their clinical condition is prone to deterio...
متن کاملLow vision: we can all do more
Despite all the treatments, operations, and medication at our disposal, there is still a significant number of people whose sight we cannot fully restore. What happens to these patients once they leave our care? Without the necessary support, advice, and low vision devices, their remaining vision will not be very good; this can make life a struggle. Support may be difficult to find, as low visi...
متن کاملSubstituent effects on aromatic stacking interactions.
Synthetic supramolecular zipper complexes have been used to quantify substituent effects on the free energies of aromatic stacking interactions. The conformational properties of the complexes have been characterised using NMR spectroscopy in CDCl(3), and by comparison with the solid state structures of model compounds. The structural similarity of the complexes makes it possible to apply the do...
