The organoplatinum complex of a primary amine and AgClO4 aggregate in methanol to oligonuclear mixed-metal species. A perchlorate salt 3 with the empirical formula C96H146Ag7Cl13N12O62Pt6 could be isolated structurally characterized help X-ray diffraction at DESY synchrotron. product contains both penta- tetra-nuclear cation which Ag(I) Pt(II) alternate, held together without any conventional b...
A powerful strategy to obtain complex supramolecular materials is the bottom-up construction of noncovalently bound materials by hierarchical self-assembly. This assembly process involves stepwise, uniform increases to the architectural complexity of a substrate, starting from discrete precursors and growing in dimensionality through controlled reactivity to a final product. Herein, two orthogo...
While mechanical bonding stabilizes tetrathiafulvalene (TTF) radical dimers, the question arises: what role does topology play in catenanes containing TTF units? Here, we report how topology, together with mechanical bonding, in isomeric [3]- and doubly interlocked [2]catenanes controls the formation of TTF radical dimers within their structural frameworks, including a ring-in-ring complex (for...
By combination of mesogenic rod-like cycloplatinated monomers based on 2,5-di(4-alkenyloxyphenyl)pyridine ligands with 1,1,3,3,5,5-tetramethyltrisiloxane, a phosphorescent, liquid-crystalline polymer was obtained, which showed polarised emission.
Platinum(II) complexes bearing acetylide ligands containing nucleobase motifs are prepared and their impact on human topoisomerase II (TopoII) is evaluated. Both platinum(II) complexes [Pt(II)(C^N^N)(C≡CCH₂R)] (1a-c) and [Pt(II)(tBu₃terpy)(C≡CCH₂R)](+) (2a-c) (C^N^N=6-phenyl-2,2'-bipyridyl, tBu₃terpy=4,4',4''-tri-tert-butyl-2,2':6',2''-terpyridyl, and R=(a) adenine, (b) thymine, and (c) 2-amino...
Robust charge-neutral Pt(II) complexes containing dianionic tetradentate bis(N-heterocyclic carbene) ligands exhibit intense blue phosphorescence in fluid solutions and in polymer films, and have been vacuum-deposited as a phosphorescent dopant in organic blue-light-emitting diodes.
