Crystalline silicon is the most important semiconductor material in the electronics industry.
However, silicon has poor optical properties because of its indirect bandgap, which prevents …

The extensive use of molecular machine-like processes in biology [1] is inspiring efforts to
exploit similarly well-controlled motions in functional synthetic systems.[2] Stimuliresponsive “…

To fully characterize the Co III –‘nitrene radical’ species that are proposed as intermediates
in nitrene transfer reactions mediated by cobalt(II) porphyrins, different combinations of cobalt…

Almost all the luminescence upconversion nanoparticles used for Förster resonant energy
transfer (FRET) applications are bare cores based on the consideration that the energy …

Cesium lead halide nanocrystals are a new attractive material for optoelectronic applications
since they combine the advantageous properties of perovskites and quantum dots. For …

Upconversion emission dynamics have long been believed to be determined by the activator
and its interaction with neighboring sensitizers. Herein this assumption is, however, shown …

It has recently become possible to synthesize mechanical devices the size of a single
molecule. Although it is tempting to regard such molecular machines as nanoscale versions of …

The mechanical behaviour of molecular machines differs greatly from that of their macroscopic
counterparts. This applies particularly when considering concepts such as friction and …

We present a class of visible-light-driven molecular motors based on barbituric acid. Due to
a serendipitous reactivity we observed during their synthesis, these motors possess a tertiary …

Donor–acceptor Stenhouse adducts (DASAs) are negative photochromes that hold great
promise for a variety of applications. Key to optimizing their switching properties is a detailed …
