Orientational Self-Sorting in Octahedral Palladium Cages: Scope and Limitations of the “cis Rule”

Kay Severin, Farzaneh Fadaei Tirani, Damien Wen Chen, Jean Charles Edouard de Montmollin, Atena-Bianca Solea

Octahedral coordination cages of the general formula Pd6L1212 were obtained by combining Pd(CH3CN)42 with heteroditopic N-donor ligands. Four different ligands were employed. These ligands have 3-pyridyl donor groups at one end and 4-pyridyl, ...

Structural Basis of Ligand Selectivity by a Bacterial Adhesin Lectin Involved in Multispecies Biofilm Formation

Corey Alfred Stevens

Carbohydrate recognition by lectins governs critical host-microbe interactions. MpPA14 (Marinomonas primoryensis PA14 domain) lectin is a domain of a 1.5-MDa adhesin responsible for a symbiotic bacterium-diatom interaction in Antarctica. Here, we show that ...

Bimodal atomic force microscopy for the characterization of thiolated self-assembled monolayers

Francesco Stellacci, Quy Ong Khac, Nikolaos Nianias, Evangelia-Nefeli Athanasopoulou

Surface coatings are becoming an integral part of materials. In recent years, molecular coatings have found larger acceptance and uses. Among them, self-assembled monolayers (SAMs) are attractive due to their inherent versatility, manufacturability, and sc ...

Characterization of Ligand Shell for Mixed-Ligand Coated Gold Nanoparticles

Francesco Stellacci, Quy Ong Khac, Zhi Luo

Gold nanoparticles owe a large number of their properties to their ligand shell. Indeed, many researchers routinely use mixtures of ligand molecules for their nanoparticles to impart complex property sets. It has been shown that the morphology of ligand sh ...

Strategies for Tuning Emission Energy in Phosphorescent Ir(III) Complexes

Mohammad Khaja Nazeeruddin, Aron Joel Huckaba

. Research into phosphorescent Ir(III) complexes has grown immensely since their first report. Talented chemists have successfully synthesized complexes capable of emitting from the UV to the near-IR regions of the electromagnetic spectrum. Tuning the emis ...

Triphenyltin(IV) adducts of diphosphoryl ligands: structural, electronic and energy aspects from X-ray crystallography and theoretical calculations

Kurt Schenk

Some triphenyltin(IV) adducts with a family of diphosphoryl ligands, RR'P(O)-X-P(O)RR' (R = OPh, Ph, R' = R, An (aniline)) and X = 1,4-OC6H4O, 1,4-OC6H4NH, 1,4-NHC6H4NH 1,4-(NHCH2)(2)C6H4, 1,3-(NHCH2)(2)C6H4 and piperazine have been synthesized and charact ...

(Arene)ruthenium Complexes with Imidazolin-2-imine and Imidazolidin-2-imine Ligands

Rosario Scopelliti, Kay Severin

Imidazolin-2-imine and imidazolidin-2-imine ligands are versatile N donors in transition metal chemistry. Here, we describe the synthesis and characterization of (arene)Ru complexes with these ligands. Simple adducts of the type [(p-cymene)Ru(L)Cl-2] (L = ...

High-Resolution Scanning Tunneling Microscopy Characterization of Mixed Monolayer Protected Gold Nanoparticles

Francesco Stellacci, Paulo Henrique Jacob Silva, Quy Ong Khac, Javier Reguera Gomez, Kellen Michael Harkness, Mauro Moglianetti, Christoph Renner

Gold nanoparticles protected by a binary mixture of thiolate molecules have a ligand shell that can spontaneously separate into nanoscale domains. Complex morphologies arise in such ligand shells, including striped, patchy, and Janus domains. Characterizat ...
