Photochromism is defined as a reversible transformation of a chemical species between two
isomers having different absorption spectra induced in one or both directions by …

Diarylethenes with heterocyclic aryl groups are newcomers to the photochromic field. They
belong to thermally irreversible (P-type) photochromic compounds. The most striking feature …

Nanoparticles (NPs) and molecular/supramolecular switches have attracted considerable
interest during the past decade on account of their unique properties and prominent roles in …

The second edition of this best-selling handbook is bigger, more comprehensive, and now
completely current. In addition to thorough updates to the discussions featured in the first …

Optical microscopes, often referred to as 'light microscopes', use visible light and a system of
lenses to provide us with magnified images of small samples. Combined with highly …

Endowing both solvent independency and excellent thermal bistability, the benzobis
(thiadiazole)‐bridged diarylethene system provides an efficient approach to realize …

Diarylethene single crystals which exhibit thermally irreversible and fatigue-resistant
photochromic reactions have been developed. Upon irradiation with ultraviolet light, the …

In this paper we demonstrate 3D two-photon recording and two-photon readout in
photochromic polymer composites containing a mixture of 1, 2-bis (2-methylbenzo [b] …

Photochemical studies on supramolecular hosts that can encapsulate small guest molecules
commonly focus on three aspects: photoswitching the cage to release or trap the guest, the …

A new type of photoswitchable fluorescent diarylethenes, which have no fluorophore unit but
emit strong fluorescence (Φf∼ 0.9) in the closed-ring isomers, has been developed. They …
