Self-assembled supramolecular cages containing ruthenium(II) polypyridyl complexes.
Substitution-inert, redox- and photo-active ruthenium(II) complexes based on 2,2',6',2''-terpyridine ligands were self-assembled into discrete supramolecular cages via coordination to palladium(II) centres and characterised by NMR, ESI-MS and X-ray crystallography.
متن کاملSelf-assembled coordination cages based on banana-shaped ligands.
The combination of pyridyl ligands and square-planar Pd(ii) or Pt(ii) cations has proven to be a very reliable recipe for the realization of supramolecular self-assemblies. This tutorial review deals with the design, synthesis and host-guest chemistry of discrete coordination cages built according to this strategy. The focus is set on structures obeying the formula [PdnL2n] (n = 2-4). The most ...
متن کاملModular self-assembled multiporphyrin cages with tunable shape.
Three new molecular cages-a trigonal prism (2) and two cubic-shaped boxes of increasing size (3, 4)-featuring as many as 10 porphyrins were obtained in quantitative yields by self-assembly of a single bis-zincporphyrin metallacycle (1) with appropriate polytopic N-linkers: the trigonal planar tpt or the cruciform porphyrins 4'-TPyP and 4'-TPhPyP.
متن کاملSelf-assembled palladium and platinum coordination cages: Photophysical studies and anticancer activity
Self-assembled coordination cages are interesting as drug delivery systems. Therefore, the synthesis of new M2L4 (M = Pd, Pt) molecular cages, derived from highly fluorescent, rigid polyaromatic ligands is reported and the first Pt2L4 cage with a ligand consisting of three pyridine moieties is described. Photophysical properties were examined showing high quantum yields of up to 48% for the m...
متن کاملHexanuclear self-assembled arene-ruthenium nano-prismatic cages: potential anticancer agents.
Two novel nano-cage compounds, 8 and 9, were prepared by self-assembly of the ruthenium complexes 4 and 5, and the tripodal donor 1. The cytotoxicity of 8 was found to be considerably stronger than that of cisplatin. The complex 8 inhibited tumor cell proliferation by interfering into regulatory pathways of the cell cycle via apoptosis.
