The construction of electronic devices from single molecular building blocks, which possess
certain functions such as switching or rectifying and are connected by atomic-scale wires on …

… We thank Christian Roth for technical support, and Peter Saalfrank for fruitful discussions.
Partial funding by the European Integrated Project PICO INSIDE and the Deutsche …

Quantum chemical calculations of various azobenzene (AB) derivatives have been carried
out with the goal to describe the energetics and kinetics of their thermal cis → trans …

The ability to control function at the molecular level by means of external stimuli is one of the
key requirements for the development of “smart” devices and materials. In particular, the use …

Photocontrol of a piperidine’s Brønsted basicity was achieved by incorporation of a bulky
azobenzene group and could be translated into pronounced reactivity differences between ON- …

The ultimate miniaturization of future devices will require the use of functional molecules at
the nanoscale and their integration into larger architectures 1 , 2 . Switches represent a …

The adsorption and switching behavior of 3,3′,5,5′-tetra-tert-butylazobenzene (meta-TBA)
are investigated by low-temperature scanning tunneling microscopy on three different …

A strategy to optimize the photoswitching efficiency of rigid, linear multiazobenzene
constructs is presented. It consists of introducing large dihedral angles between azobenzene …

Relapse occurs in 50% of patients receiving radiation for clinical stage (CS) I and II nodal
and extranodal non-Hodgkin's lymphoma (NHL). Prior to the introduction of intensive …

… However, the overall spectral shape and in particular the 500 mV shift between d-TPP and
b-TPP can be clearly seen. When manipulating the molecule back toward its initial position on …
