Self-assembly of cucurbit[7]uril based triangular [4]molecular necklaces and their fluorescence properties.

ABSTRACT: Self-assembly of rigid-rod dipyridine ligand 1 with M(en)(NO₃)₂ (M = Pd, Pt) affords triangular (3, 5) and square (4, 6) supramolecular coordination complexes (SCCs). The binding affinity of 1 toward CB[n]-type containers results in the formation of triangular [4]molecular necklaces ([4]MNs, 7-10) by either one-pot or post complexation approaches as evidenced by ¹H NMR, diffusion ordered spectroscopy, and ESI-MS.
