✦ Synopsis

Besides serving merely as colorants, functional organic dyes have become increasingly important in materials science."] With applications like photovoltaics[*] or electroluminescence,[31 they can be considered as a direct link between electronics and optics, being capable of performing both as the electroactive and the light absorbing/emitting entity. However, in the liquid or solid state, the electronic properties do not arise from individual molecules but are rather governed by the whole collective. Hence, it is necessary to understand and to control the supramolecular packing of a given chromophore, if its full potential as a functional material is to be estimated.

Linear tran~-quinacridone[~] 1 (Scheme 1) is a widely used organic pigment, that exhibits excellent fastness properties[51 as lo
