The scanning tunneling microscope enables atomic-scale measurements of electron
transport through individual molecules. Copper phthalocyanine and magnesium porphine …

Iron tetraphenylporphyrin chloride (FeTPPCl) adsorbed on a Au (111) substrate is
investigated using low-temperature scanning tunneling microscopy. Cl is controllably …

We investigated dibenzo [a, h] thianthrene molecules adsorbed on ultrathin layers of NaCl
using a combined low-temperature scanning tunneling and atomic force microscope. Two …

The nonequilibrium triplet state of molecules plays an important role in photocatalysis,
organic photovoltaics, and photodynamic therapy. We report the direct measurement of the …

We have manipulated single azobenzene molecules using several different techniques with
a variable-temperature scanning tunneling microscope (STM). Isolated azobenzene …

Molecular switches are of fundamental importance in nature, and light is an important
stimulus to selectively drive the switching process. However, the local dynamics of a …

One of the key challenges in chemistry is to break and form bonds selectively in complex
organic molecules that possess a range of different functional groups. To do this at the …

Atomic force microscopy (AFM) as well as scanning tunneling microscopy induced light
emission (STM-LE) are, each on their own, powerful tools used to investigate a large variety …

A covalent bond between an individual pentacene molecule and a gold atom was formed by
means of single-molecule chemistry inside a scanning tunneling microscope junction. The …

Electron transfer plays a crucial part in many chemical reactions,, including photosynthesis,
combustion and corrosion. But even though redox-state transitions change the electronic …
