Self-Assembled Containers Based on Extended Tetrathiafulvalene
Two
original self-assembled containers constituted each by six
electroactive subunits are described. They are synthesized from a
concave tetratopic π-extended tetrathiafulvalene ligand bearing
four pyridyl units and <i>cis</i>-M(dppf)(OTf)<sub>2</sub> (M = Pd or Pt; dppf = 1,1′-bis(diphenylphosphino)ferrocene;
OTf = trifluoromethane-sulfonate) complexes. Both fully characterized
assemblies present an oblate spheroidal cavity that can incorporate
one perylene molecule

Electron-Rich Arene–Ruthenium Metalla-architectures Incorporating Tetrapyridyl–Tetrathiafulvene Donor Moieties
A series of arene ruthenium architectures
have been prepared from
coordination-driven self-assembly using dinuclear <i>p</i>-cymene ruthenium acceptors and π-donating tetratopic tetrapyridyl–tetrathiafulvalene
donor ligands. The synthetic strategy, based on a geometric interaction
approach, leads to four electroactive metalla-assemblies, <b>1</b>–<b>4</b> (one molecular cube and three metallaplates),
that were characterized by NMR, ESI-MS, X-ray diffraction, and cyclic
voltammetry. Rationalization of their formation discrepancy was completed
by DFT calculations supported by structural features of their constituting
TTF and Ru-complex components. Metalla-architectures possessing electron-rich
cores (<b>3</b>, <i>cis-</i><b>4</b>, and <i>trans</i>-<b>4</b>) interact strongly with picric acid
(PA) to yield cocrystallized products, PA + metalla-assemblies, confirmed
by single-crystal X-ray structure analyses
