Discrete double-to-quadruple aromatic stacks: Stepwise integration of face-to-face geometries in cocrystals based on indolocarbazole

Abstract

One, two, three, four: An indolocarbazole organizes double, triple, and quadruple stacks of aromatic molecules within multicomponent solids. The aromatic units are sequentially integrated into discrete assemblies and undergo [2+2] photodimerization. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
