title: A Four-Component Heterometallic Cu-Pt Quadrilateral via Self-Sorting.
abstract: Herein we combine the subcomponent self-assembly and integrative self-sorting techniques with the well-established platinum(II)-pyridine coordination-driven self-assembly to report the quantitative synthesis and spectroscopic characterization of a heterometallic CuI-PtIIquadrilateral QL that is formed from a total of twelve molecular components from four unique species, including 5-(pyridin-4-ylethynyl)picolinaldehyde (1), p-toluidine (2), [Cu(CH3CN4](PF6) (3), and cis-Pt(PEt3)2(OTf)2(4), in a 4:4:2:2 ratio. Despite the many different entities potentially forming from these four precursor units, the clean formation of QL is mainly guided by the different coordination preferences of the metal ions 3 and 4, and the design criteria inherent in compounds 1 and 2.
