The self-assembly of chiral depsipeptide dendrons 4, which contain a cyanuric acid building block at their focal point, with the homotritopic Hamilton receptor 1 is reported. The 1:3 compositions of the resulting chiral supramolecular dendrimers, the association constants K, and the cooperativity of binding expressed by Scatchard plots and the Hill coefficients n was determined by NMR titration experiments. The most pronounced positive cooperativity was found for the complexes 1L with L being the second-generation dendrons 4c-e. The least stable complexes are formed with the bulky third-generation dendrons 4f-h. Similar results are obtained by the corresponding complexation of the achiral Frechét-type first- to third-generation dendrons 3 with 1. Chiroptical investigations of 1:3 complexes of 1 and 4 reveal chirality transfer from the dendron to the Hamilton receptor as demonstrated by the appearance of new CD absorption bands at 310 nm. © 2006 Wiley-VCH Verlag GmbH & Co.
