Implications of Stoichiometry-Controlled Structural Changeover Between Heteroleptic Trigonal [Cu(phenAr<sub>2</sub>)(py)]<sup>+</sup> and Tetragonal [Cu(phenAr<sub>2</sub>)(py)<sub>2</sub>]<sup>+</sup> Motifs for Solution and Solid-State Supramolecular Self-Assembly
complexes) opens the venue to heteroleptic metallosupramolecular HETPYP-I assemblies both in solution and the solid state, involving the trigonal [Cu(phenAr2)(py)]+ coordination motif (phenAr2 = 2,9-diarylphenanthroline; py = various oligopyridines). Combining the same building blocks at another stoichiometric ratio furnished metallosupramolecular HETPYP-II aggregates in the solid state, now based on the
a series of star-shaped pyridine, bipyridine, and terpyridine derivatives is reported by using a modular approach that combines the use of a ligand, spacer, and core unit. A fairly efficient method to prepare 4′-nonafloxy-functionalized terpyridine derivatives is described. The building blocks that contain the functionalizedpyridine, bipyridine, or terpyridine derivatives were linked to different

scattering experiments in solution using a synchrotron source. Photoexcitation of the prismatic assemblies reveals that efficient, through-space energytransfer occurs between the macrocyclic dimers within the prisms. The distance dependence of energytransfer between the faces of the prisms was observed by varying the size of the prismatic assemblies through the use of 3-fold symmetric ligands having
