200 years ago M. Faraday discovered benzene, but we are still learning about it. Just published in @acsnano, we show that direct interaction over 1 nm orders a network of benzene rotors mounted on triangular platforms. @kieluni @CFMdonostia @ESIMproject pubs.acs.org/doi/full/10.102…

Orientational Order of Phenyl Rotors on Triangular Platforms on Ag and Au(111)

We investigated trioxatriangulenium functionalized with phenyl (phenyl-TOTA) on the (111) surfaces of Ag and Au using low-temperature scanning tunneling microscopy (STM) and density functional theory...

Just published! Hot paper in @angew_chem in collaboration with @Empa_CH @TTorresGroup @SHUSurfaceLab @UAM_Madrid @IAdChem @DIPCehu @CFMdonostia Opening thread 👇 onlinelibrary.wiley.com/doi/…

Tailoring π--d$\pi {\text{--}}d$ Magnetic Interactions in Metallated Porphyrin Nanotapes

To understand how π$\pi$-radicals and d$d$-electrons interact within molecular nanostructures, we have studied metallated porphyrin nanotapes synthesized on gold surfaces. We reveal element-specific...

These are fascinating systems showing the magic of porphyrins and how powerful on-surface synthesis can be to create new chemical compounds. Finally, I want to thank everybody involved in this quite fruitful collaboration. Good job everyone!

We show an electrically controlled Fe–FePc molecular spin switch that reversibly changes its magnetic state and shifts a nearby spin’s resonance, showing potential of scalable, electrically tunable molecular quantum devices.
