Self-Assembled Supramolecular Squares from Chiral [4,4']-Bipyridines
Self-Assembled Supramolecular Squares are synthesised from two different building blocks: Bidentate metal complexes (90°, palladium and platinum) ......

Orientation reversal of manifolds
(2009-03-06)
We study the phenomenon of chirality in the context of manifolds. An orientable manifold is called amphicheiral if it admits an orientation-reversing self-map and chiral if it does not. In addition to being continuous and ...
