Two-dimensional supramolecular architectures and metallic nanostructures on pre-structured surfaces studied by scanning tunneling microscopy

In this thesis, we present Scanning Tunneling Microscopy investigations of two-dimensional supramolecular architectures and metallic nanostructures on pre-structured surfaces. We studied different self-assembled supramolecular architectures formed by linea ...

Fabrication of Dendritic Gold Nanoparticles by Use of an Ionic Polymer Template

Paul Joseph Dyson, Zhaofu Fei, Dongbin Zhao

A facile method for the fabrication of dendritic gold nanoparticles (NPs) by use of an ionic polymer template has been developed. In situ generation of an imidazolium-based (cationic) polymer, poly[1-methyl-3-(4-vinylbenzyl)imidazolium], with AuCl4- counte ...

Tuning the self-assembly of lanthanide triple stranded heterobimetallic helicates by ligand design

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

The heterobitopic ligands LAB4 and LAB5 have been designed and synthesised with the ultimate aim of self-assembling dual-function lanthanide complexes containing either a magnetic and a luminescent probe or two luminescent probes emitting at different wave ...

Toward the Rational Design of Lanthanide Coordination Polymers: a New Topological Approach

Jean-Claude Bünzli, Marinella Mazzanti

The implementation of four bidentate building blocks into a highdenticity linker with a flexible spacer leads to a predisposed ligand that allows one to direct the self- assembly of 1D functional coordination polymers. This is illustrated by the assembly u ...

Selective Self-Assembly of Hexameric Homo- and Heteropolymetallic Lanthanide Wheels: Synthesis, Structure, and Photophysical Studies

Jean-Claude Bünzli, Marinella Mazzanti

A rational approach to the formation of pure heteropolymetallic lanthanide complexes that uses a two-step assembly strategy and exploits the different size requirements of the two metals included in the final structure is described. The investigation of th ...

A PCP-Pincer RuII-Terpyridine Building Block as a Potential "Antenna Unit" for Intramolecular Sensitization

André Merbach

The redox- and photoactive mononuclear complex [Ru(PCP)(tpy-DTTANa4)]Cl {PCP = [C6H3(CH2PPh2)2-2,6]-; tpy-DTTA4- = 4'-(2,2':6',2''-terpyridine)-diethylenetriamine-N,N,N'',N''-tetraacetate} possesses an externally directed, vacant N3O4 polyaminocarboxylate- ...

The influences of location awareness on computer-supported collaboration

Nicolas Nova

"Where are you?". This recurring question when opening a mobile conversation attests the importance of spatialisation in social interactions. More and more applications support mutual location-awareness: they enable members of a group to locate their partn ...

Thermodynamic Parameters Governing the Self-Assembly of Head–Head–Head Lanthanide Bimetallic Helicates

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

Abstract: The heterobitopic ligands LABX (X=1,2, 3,4 or 5),diff ering only by a Cl or NEt2 substituent,have been designed to complex with a pair of lanthanide ions to form triple-stranded bimetallic helicates of overall composition [Ln2ACHTUNGTRENUNG(LABX) ...

Monitoring Two-Dimensional Coordination Reactions: Directed Assembly of Co−Terephthalate Nanosystems on Au(111)

Klaus Kern, Harald Brune, Sylvain Clair

We report scanning tunneling microscopy observations on the formation of 2D Co-based coordination compounds on the reconstructed Au(111) surface. Preorganized arrays of Co bilayer islands are shown to be local reaction sites, which are consumed in the form ...

Formation of aminosilane-oxide interphases

Véronique Michaud, Yves Leterrier, Gabrielle Pax

The aim of this work is to understand the interactions and interphase formation mechanisms between a liquid aminosilane oligomer (γ -APS) and glass, steel or gold surfaces as a function of the pH of the liquid aminosilane. When basic liquid γ -APS (pH 11.4 ...
