We report the preparation of a helical complex and its study in molecular junctions. We show that the SAMs of this racemic compound present electrically robust behaviour which will pave the way for future studies on the CISS effect with analogous enantiopure compounds.

Redox-responsive supramolecular gels involving highly ordered assemblies of small molecules that can exist in different stable oxidation states are very promising soft materials for many applications ranging from catalysis to electronics. Stimulation of such materials has however so far relied mainly on the addition of chemical fuels (oxidizing or reducing agents) which makes the reversibility ...

A 1D coordination compound made of a photochromic dithienylethene linker and borate counterions is reported. Full photoconversion from the closed isomer to the open isomer of the dithienylethene within single crystals allow for monitoring of the transformation by photocrystallography. Magnetic slow relaxation as well as magnetic hysteresis are observed ...

Pre-ICMM Meetings: Olivier Kahn Discussions (OKD) Three Pre-ICMM2025 meetings will take place in downtown Paris between October the 23rd, 2 pm and October the 24th, 6 pm. They are organized as three parallel synchronized sessions on the three main topics: Molecular Magnets, Spin Crossover Materials, and Molecular Spintronics including three plenary lectures common to the three satellites. The oral contributions are only on invitation. Registration: free but mandatory (limited number of ...

In the submonolayer regime, fullerene molecules tend to form compact islands on dense-packed metal surfaces. On Cu(111), these islands exhibit various types of corrugation patterns caused by a compressive epitaxial stress and an atomic-scale reconstruction of the metal surface. Following a strategy we introduced in a previous study , we ...

We report here the reversibility and bistability of the switching behavior in an azobenzene derivative induced by the bias applied by a scanning-tunneling microscopy (STM) tip, at low temperature and in ultra-high vacuum environment. This cis-to-trans and trans-to-cis switching were observed during STM imaging in either polarity at +2 V or −2 V, on a ...

There has been considerable interest in building switching functions into self-assembled monolayers with switching actuated by external stimuli such as light, electrical current, heat, pressure or chemical changes. In this study, dual switching functionality has been built into azobenzene based molecular monolayers. Switching behaviour has been compared for unsubstituted azobenzene monolayer adsorbates and two other ...
