An active and directional hydroxide transport is realized by using PtII organometallic compounds as carriers based on their hydrolysis reaction combined with the different permeability of the neutral form and the charged form PtII aqua species. These compounds can transport hydroxide selectively “uphill”, a gradient in a liposomal system producing a transmembrane pH gradient, and tuneable activity is

The design and self-assembly of three supramolecular triangles is described. A novel 601 corner unit directs the exclusive formation of triangular assemblies that are not in detectable equilibrium with other macrocycles. The resulting triangles have sides ranging from 2.7 to 3.5 nm in length and molecular masses as high as 5396 amu. The crystal structure of one of the assemblies shows an similar to1.4 nm cavity; the crystal packing forms open, triangular channels. The characterization of the supramolecular triangles by multinuclear NMR, elemental analysis, and electrospray mass spectrometry is also reported.
