Synthesis of triple stranded porphyrin nanobelts Open
Molecular nanobelts are fascinating analogs of carbon nanotubes. Their rigid geometries and strongly coupled π-electrons have the potential to generate a wave function resembling that of a quantum ring. Here, we report the synthesis of tri…

An 18-Porphyrin Nanoring at the Size Limit for Global Aromaticity Open
What is the size limit for global aromaticity? How large can a macrocyclic π-system be and still exhibit an aromatic ring current around its circumference? We address this question by investigating a π-conjugated butadiyne-linked 18-porphy…

A molecule with half-Möbius topology Open
Stereoisomers of C$_{13}$Cl$_2$ exhibiting helical orbitals around a ring of carbon atoms were synthesized by atom manipulation on NaCl surfaces. We resolved the enantiomeric geometries of the closed-shell singlet states by atomic force mi…
