Lanthanide-porphyrin species as Kondo irreversible switches through tip-induced coordination chemistry (NANOSCALE 2021)

Metallosupramolecular chemical protocols are applied to in situ design dysprosium porphyrin complexes on Au(111) by sequential deposition of 2H-4FTPP species and Dy, resulting in the production of premetallated Dy-2H-4FTPP, partially metallated Dy-1H-4FTPP and fully metallated Dy-0H-4FTPP complexes, as determined by scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. A zero…

A Trapezoidal Octacyanoquinoid Acceptor Forms Solution and Surface Products by Antiparallel Shape Fitting with Conformational Dipole Momentum Switch (ANGEW. CHEM. 2021)

A new compound (1) formed by two antiparallelly disposed tetracyano thienoquinoidal units has been synthesized and studied by electrochemistry, UV/Vis-NIR, IR, EPR, and transient spectroscopy. Self-assembly of 1 on a Au(111) surface has been investigated by scanning tunneling microscopy. Experiments have been rationalized by quantum chemical calculations. 1 exhibits a…

Surfaces open new routes: unexpected formation of m-PANI oligomers from p-aminophenol (ANGEW. CHEM. 2020)

Surfaces never fail to surprise. Once more, they have demonstrated that chemistry on 2D metallic surfaces behaves differently to that on solution (3D). We have shown that highly unspecific solution-based Michael addition transforms into highly selective when carried out on a Pt(111) surface. In this way, we are able to…
