Fig. 3. Amphipathic metallohelices. Views (a) and (b) of opposite faces of triplex metallohelix 11 and the corresponding hydrophobicity plots (c) and (d) where coloured spheres indicate the DFT-calculated positions and energies of associated water O-atoms. The most hydrophobic regions (red) correspond to the π-stacked arenes colourized pink in (a) and (b).
