“…Crystallographic analyses revealed the expected square structure of 3 ( Figure 2). [22] The N-Pt-N angles have values comprised between 83-858, similar to what was reported for other square structures based on bisphosphine Pt corners.…”

Self‐Assembly of a Giant Molecular Solomon Link from 30 Subcomponents

et al. 2014

The synthesis of topologically complex structures, such as links and knots, is one of the current challenges in supramolecular chemistry. The so-called Solomon link consists of two doubly interlocked rings. Despite being a rather simple link from a topological point of view, only few molecular versions of this link have been described so far. Here, we report the quantitative synthesis of a giant molecular Solomon link from 30 subcomponents. The highly charged structure is formed by assembly of 12 cis-blocked Pt(2+) complexes, six Cu(+) ions, and 12 rigid N-donor ligands. Each of the two interlocked rings is composed of six repeating Pt(ligand) units, while the six Cu(+) ions connect the two rings. With a molecular weight of nearly 12 kDa and a diameter of 44.2 Å, this complex is the largest non-DNA-based Solomon link described so far. Furthermore, it represents a molecular version of a "stick link".

“…Although all complexes with a pyridyl framework gave consistent electrospray MS data, the signals for the palladium complexes were less intense compared with the platinum complexes. In contrast, no signals at all were observed for the cyano- coordinated complexes 6 and 8, probably because of the much weaker late transition metal-nitrile bond energies (44), which likely decreased the lifetime of the charged species in the mass spectrometer because of dissociation under the harsh conditions.…”

“…Shown in Figure 1 is a representative example: an X-ray determined structure of a single crystal of [Pt(4,4′-bipyridyl)(dppp)(OTf) 2 ] 4 , 1 (dppp ) diphenylphosphinopropane; OTf ) trifluoromethanesulfonate). 25 Omitted from the structure, for clarity, are eight counteranions per cationic metallocycle unit. The omitted ions occupy primarily the cavity/channel region of the structure, thereby largely precluding the idea of achieving nanoscale porosity.…”

An enormous number and variety of discrete, isolable, supramolecular-coordinationchemistry-based assemblies featuring well-defined nanoscale cavities have been designed, synthesized, and characterized over the past decade. A small number of these have subsequently been used as building blocks for microporous materials and now comprise an important component of an emerging chemistry of microporous molecular materials. The extant materials typically have displayed large void volumes, high internal surface areas, and the ability to withstand the systematic removal of solvent. These and other properties (chemical tailorability, alignment of cavities to form extended channels, good processability, etc.) suggest a number of potentially very exciting applications involving selective molecular transport, sensing, or chemical transformationswith many of these now supported by proofof-concept experiments.
