Abstract

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 Cu I ‐Pt II quadrilateralQL 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(CH3 CN4 ](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 ofQL is mainly guided by the different coordination preferences of the metal ions3 and4, and the design criteria inherent in compounds1 and2 . Abstract : Self‐sorting things out : This work demonstrates a novel multicomponent self‐assembly technique that combines the subcomponent self‐assembly, the platinum (II)‐pyridine coordination‐driven self‐assembly and integrative self‐sorting in a one‐pot process. The robustness of this approach was demonstrated by quantitatively preparing the self‐assembled four‐component heterometallic Cu I ‐Pt II quadrilateralQL .
