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 Cu-I-Pt-II quadrilateral 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.
