Coordination-driven self-assembly strategy has demonstrated the efficiency and versatility to construct well-ordered supramolecular coordination complexes (SCCs) such as discrete metallacycles and metallacages. In recent years
it has aroused tremendous interest to build more complexed self-assembled structures
via
the implementation of additional non-covalent recognition motifs on the SCCs platform. In this work
we have successfully attained this objective
with the elaborate manipulation of non-interfering pyridine-Pt
2+
and molecular tweezer/guest complexation in a hierarchical self-assembly manner. The resulting SCCs-based linear supramolecular polymers exhibit intriguing NIR-emissive behaviors
primarily attributed to the presence of intermolecular Pt(Ⅱ)-Pt(Ⅱ) metal-metal interactions in the non-covalent tweezering structure. Hence
supramolecular engineering of multiple non-covalent interactions offers a feasible avenue toward functional materials with tailored properties.
