Amplification of chirality in two-dimensional molecular lattices


Ernst, K H (2008). Amplification of chirality in two-dimensional molecular lattices. Current Opinion in Colloid & Interface Science, 13(1-2):54-59.

Abstract

Induction of homochirality on surfaces via cooperatively amplified interactions in molecular monolayers is a new phenomenon of supramolecular surface chirality. Prochiral molecules will turn into either handedness upon adsorption, but doping with intrinsically chiral molecules breaks further symmetry and induces homochirality. A similar effect is observed at small enantiomeric excess among chiral molecules. The excess molecules provide the chiral bias that becomes amplified into single lattice chirality.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
