Self-assembling of nanoscopic molecular rectangles, extended helicates and porous-like materials based on macrocyclic dicopper building blocks under fine supramolecular control.

Upon reaction with a dicarboxylate linker, macrocyclic dicopper complexes encode for a selective supramolecular 2 + 2 self-assembly of nanoscopic rectangles, a new class of molecular helicates, and porous-like materials via fine structural control at three supramolecular levels.
