%X A strategy to engineer the stacking of diketopyrrolopyrrole (DPP) dyes based on non-statistical metallosupramolecular self-assembly is introduced. For this, the DPP backbone is equipped with nitrogen-based donors that allow for different discrete assemblies to be formed upon the addition of Pd(II), distinguished by the number of π-stacked chromophores. A Pd<sub>3</sub>L<sub>6</sub> three-ring, a heteroleptic Pd<sub>2</sub>L<sub>2</sub>L′<sub>2</sub> ravel composed of two crossing DPPs (flanked by two carbazoles), and two unprecedented self-penetrated motifs (a Pd<sub>2</sub>L<sub>3</sub> triple and a Pd<sub>2</sub>L<sub>4</sub> quadruple stack), were obtained and systematically investigated. With increasing counts of stacked chromophores, UV/Vis absorptions red-shift and emission intensities decrease, except for compound Pd<sub>2</sub>L<sub>2</sub>L′<sub>2</sub>, which stands out with an exceptional photoluminescence quantum yield of 51
