Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <italic> <bold>Strictly periodic assemblies …︁</bold> </italic> …︁ of porphyrin units deposited on functionalized substrates can be used to realize solar cells with remarkable efficiency. In their Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 7441 ff.</ext-link>, J. Liu, C. Wöll, and co‐workers show by electronic‐structure calculations that ordered arrays of porphyrins have a small dispersion of occupied and unoccupied bands leading to the formation of a small indirect band gap. Such ordered porphyrin metal–organic frameworks (MOFs) are then grown using a layer‐by‐layer liquid‐phase epitaxy.<graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjssphdjb" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
