A D3h-symmetry hexaazatriphenylene-tris-N-heterocyclic carbene ligand and its coordination to iridium and gold: preliminary catalytic studies
Royal Society of Chemistry (2017)A new D3h-symmetry tris-N-heterocyclic carbene ligand has been prepared and coordinated to iridium and gold. The ligand contains an electron-poor hexaazatriphenylene core; thus, the resulting tris-NHC ligand is a poor ... -
A Matter of Fidelity: Self‐Sorting Behavior of Di‐Gold Metallotweezers
Wiley (2019-06)Cation‐induced high selective self‐sorting is observed for reactions involving a series of di‐gold metallotweezers. The variation of the nature of the arms of the tweezers (benzo‐imidazolylidene or pyrene‐imidazolylidene), ... -
A Redox-Switchable Gold(I) Complex for the Hydroamination of Acetylenes: A Convenient Way for Studying Ligand-Derived Electronic Effects
American Chemical Society (2022-03-31)A gold complex with a naphthalene-di-imide-functionalized N-heterocyclic carbene (NHC) ligand was prepared and characterized. The electrochemical studies reveal that the complex is able to undergo two successive reduction ... -
A Rigid Trigonal‐Prismatic Hexagold Metallocage That Behaves as a Coronene Trap
Wiley (2019-05-13)A trigonal‐prismatic hexagold cage was obtained by combining a triphenylene‐tris(N‐heterocyclic carbene) ligand and a carbazolyl‐bis(alkynyl) linker. The metallocage has a slot‐like cavity with a volume of about 300 Å3. ... -
Cation-Driven Self-Assembly of a Gold(I)-Based Metallo-Tweezer
Wiley (2017-08-07)A combination of self-complementary pi-pi-stacking interactions and metallophilic interactions triggered the self-assembly of a new digold(I) metallo-tweezer in the presence of several types of M+ ions. Titrations by ... -
Chemically Tunable Formation of Different Discrete, Oligomeric, and Polymeric Self‐Assembled Structures from Digold Metallotweezers
(2018)Digold metallotweezers whose complex supramolecular landscape is controlled by adding a series of metal cations are described. The metallotweezers have a strong tendency to form interesting supramolecular structures on ... -
Clippane: A Mechanically Interlocked Molecule (MIM) Based on Molecular Tweezers
Wiley (2022-01-10)In this study we report the preparation of a new mechanically interlocked molecule formed by the self-aggregation of two metallotweezers composed by two pyrene-imidazolylidene gold(I) arms and a pyridine-centered pentacyclic ... -
Dimensional Matching versus Induced‐Fit Distortions: Binding Affinities of Planar and Curved Polyaromatic Hydrocarbons with a Tetragold Metallorectangle
Wiley (2020-04-20)A tetragold(I) rectangle‐like metallocage containing two pyrene‐bis‐imidazolylidene ligands and two carbazolyl‐bis‐alkynyl linkers is used for the encapsulation of a series of polycyclic aromatic hydrocarbons (PAHs), ... -
Gold(I) Metallo‐Tweezers for the Recognition of Functionalized Polycyclic Aromatic Hydrocarbons by Combined π–π Stacking and H‐Bonding
Wiley (2017)Two gold(I)‐based metallo‐tweezers with bis(Au−NHC) pincers and a carbazole connector have been obtained and used for the recognition of polycyclic aromatic hydrocarbons (PAHs). In the case of the tweezer with pyrene–NHC ... -
Preparation and self-aggregation properties of a series of pyrene-imidazolylidene complexes of gold (I)
Elsevier (2020-06-21)This article describes the preparation of three different Au(I) complexes bearing a pyrene-imidazolylidene ligand, two of which are bound to phenyl-acetylene ligands. The supramolecular and photophysical properties of all ... -
Reversible Formation of Gold Halides in Single‐Crystal Hybrid‐Perovskite/Au Interface upon Biasing and Effect on Electronic Carrier Injection
Wiley (2019-08-08)Solar cells, light emitting diodes, and X‐ray detectors based on perovskite materials often incorporate gold electrodes, either in direct or indirect contact with the perovskite compound. Chemical interactions between ... -
Self-Assembly of Di-N-Heterocyclic Carbene-Gold-Adorned Corannulenes on C60
Wiley (2017-08-04)The deprotonation of a corannulene-based bisazolium salt allowed the preparation of a corannulene-based NHC di-AuI complex. The prepared di-AuI-complex was tested in the recognition of fullerene-C60, demonstrating good ... -
