Coordination-driven self-assembly that combines rigid ditopic Pt(II) metal acceptors and bis-pyridyl organic donors provides a facile means of synthesizing well-defined metallacycles of predetermined size and geometry. Functionalization of the component acceptor or donor building blocks allows for the preparation of multifunctional supramolecular materials wherein the stoichiometry and position of individual functional moieties can be precisely controlled. The design, self-assembly, and applications of polyfunctional supramolecules incorporating functional moieties with host-guest, photonic, materials, and self-organizational properties is discussed.
