Synthesis, characterization and molecular recognition of a bis-platinum terpyridine dimer

Abstract

A novel bis-platinum(II) terpyridine-based macrocycle has been quantitatively obtained by self-assembly; the Pt(II) host binds neutral planar and electron-rich aromatic guests with good selectivity in DMSO.

Synthesis, characterization, solid-state photo-luminescence and anti-tumor activity of zinc(II) 4′-phenyl-terpyridine compounds

“…The coordination chemistry of terpyridine is attracting a current attention, leading to complexes with different metal ions and photoluminescent properties [1][2][3][4][5][6][7][8], in particular those of platinum and palladium [9][10][11][12], silver and cadmium [13][14][15][16]. The complexes can be of significance, e.g.…”

A Self‐Assembled Rectangular Host with Terpyridine–Platinum(II) Moieties That Binds Unsubstituted Pentacene in Solution

“…Pentacene (purified by sublimation) was purchased from TCI Co., Ltd. 1 H NMR, 13 19 F NMR spectroscopy measurements. Pentacene (purified by sublimation) was purchased from TCI Co., Ltd. 1 H NMR, 13 19 F NMR spectroscopy measurements.…”

“…Host 1 8+ has two pairs of terpyridine-Pt II moieties that are aligned parallel to each other and connected by diyne linkers. Terpyridine complexes of square-planar metals, such as Pd II and Pt II , which possess large π surfaces, have been utilized in receptors for aromatic guests by us [13] and others. [14] The diyne linkers connect two terpyridine molecules by π conjugation without steric hindrance to produce a parallel arrangement of the terpyridine moieties, and they realize a flatter conformation than other linkers such as para-oligophenylenes.…”

“…For example, Nabeshima and coworkers synthesised a ligand with a terpyridine site, a biphenyl linker, and a monodentate pyridyl site (L15). [33] The combination of a 2 : 1.85 molar ratio of this ligand with [Pt(COD) (BF 4 ) 2 ] in a mixed acetone/acetonitrile/chloroform solution gave a [Pt 2 L15 2 ] 4 + complex (Figure 12). In DMSO, the cavity of this structure was suitable for the encapsulation of planar aromatic guests, and bound a swathe of these in 1 : 1 stoichiometry, including naphthalene and benzene units substituted with diols, hydroxyls, and dichlorides.…”
