Using scanning probe microscopy techniques, at low temperatures and in ultrahigh vacuum,
individual molecules adsorbed on surfaces can be probed with ultrahigh resolution to …

Carbon allotropes built from rings of two-coordinate atoms, known as cyclo [n] carbons, have
fascinated chemists for many years, but until now they could not be isolated or structurally …

Triangulene, the smallest triplet-ground-state polybenzenoid (also known as Clar's
hydrocarbon), has been an enigmatic molecule ever since its existence was first …

Petroleum is one of the most precious and complex molecular mixtures existing. Because of
its chemical complexity, the solid component of crude oil, the asphaltenes, poses an …

Controlling selectivity of reactions is an ongoing quest in chemistry. In this work, we
demonstrate reversible and selective bond formation and dissociation promoted by tip …

The structure determination of surface species has long been a challenge because of their
rich chemical heterogeneities. Modern tip-based microscopic techniques can resolve …

Resolving individual atoms has always been the ultimate goal of surface microscopy. The
scanning tunneling microscope images atomic-scale features on surfaces, but resolving …

The formation of excitons in organic molecules by charge injection is an essential process in
organic light-emitting diodes (OLEDs),,,,,–. According to a simple model based on spin …

Incipient soot early in the flame was studied by high-resolution atomic force microscopy and
