Light offers unique opportunities for controlling the activity of materials and biosystems with
high spatiotemporal resolution. Molecular photoswitches are chromophores that undergo …

The field of photopharmacology uses molecular photoswitches to establish control over the
action of bioactive molecules. It aims to reduce systemic drug toxicity and the emergence of …

Biological processes are naturally regulated with high spatial and temporal control, as is
perhaps most evident in metazoan embryogenesis. Chemical tools have been extensively …

Chemistry, pure and applied, is a science and an industry. By its power over the expressions
of matter, it also displays the creativity of art. It has expanded from molecular to …

Spatial and temporal control over chemical and biological processes, both in terms of
“tuning” products and providing site‐specific control, is one of the most exciting and rapidly …

A straightforward synthesis of azobenzenes with bathochromically‐shifted absorption bands
is presented. It employs an ortho‐lithiation of aromatic substrates, followed by a coupling …

Molecular systems that can be remotely controlled by light are gaining increasing
importance in cell biology, physiology, and neurosciences because of the spatial and …

A strategy to expand anti‐Stokes shifting from the far‐red to deep‐blue region in metal‐free
triplet–triplet annihilation upconversion (TTA‐UC) is presented. The method is demonstrated …

Light‐mediated coupling of acylsilanes with indoles is reported. This photo click reaction
occurs under mild conditions (415 nm) mostly in quantitative yield and provides stable …

Chemical reactions are classically controlled by the judicious choice of functional groups as
well as external factors such as temperature and catalysts. However, the use of light …
