Self‐Organization of Dendritic Supermolecules, Based on Isocyanide–Gold(I), –Copper(I), –Palladium(II), and –Platinum(II) Complexes, into Micellar Cubic Mesophases

First‐ and second‐generation dendrimers with an isocyanide group as the focal functional point (CN‐G n ; n : 1,2) and their corresponding organometallic complexes [MCl(CN‐G n )] (M: Au, Cu), [{CuCl(CN‐G n ) 2 } 2 ], and trans‐ [MI 2 (CN‐G n ) 2 ] (M: Pd, Pt) have been synthesized. The free ligands and the first‐generation complexes do not show mesogenic behavior, but all of the second‐generation complexes display a thermotropic micellar cubic mesophase, over a large temperature range, and some of them directly at room temperature. The structure of the mesophase consists of the packing of two, discrete polyhedral micellar aggregates in a three‐dimensional cubic Im $\bar 3$ m lattice.
