Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Combining helicate and helicene chemistry</bold>: Pentadentate phosphole‐pyridine helicands (see scheme) coordinated to Cu^I or Ag^I centers afford configurationally stable double‐stranded helicates bearing multiple bridging‐phosphane coordination modes. Similarly enantiomerically pure helicene‐grafted helicands afford enantiopure helicates.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1v4b115q" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
