Extending the spectral response of viologen-based electrochromic devices to the near-infrared region is essential to enhance their performance for smart window applications. Although synthetic and formulation modifications have been proposed to achieve this goal, these strategies always come at the expense of deteriorating the electrochromic behavior of the system. [...]

Offering high spatiotemporal resolution, dual wavelength-controlled soft matter network formation paves the way to advanced printing techniques with optimized performance. One of the most promising approaches is the antagonistic control of covalent bond-forming reactions with two colors of light, where photoexcitation with one wavelength induces a photochemical reaction, while irradiation with the other ceases it in the presence of the first color. [...]

Incorporating photoisomerizable moieties within drugs offers the possibility of rapid and reversible light-dependent switching between active and inactive configurations. Here, we developed a photoswitchable adenosine A3 receptor (A3R) agonist that confers optical control on this G protein-coupled receptor through noninvasive topical skin irradiation in an animal model of psoriasis.

The reversible modulation of acidity using molecular photoswitches enables the remote control of a variety of (bio)chemical processes with light. Herein we investigated the structural features that allow amplifying photoinduced p K variation in phenol-diarylethene conjugates, which toggle between low- and high-acidity states by switching the conjugation between the ionizable moiety and electron-withdrawing groups upon photoisomerization.

Luminescent materials are emerging promising tools for digital data encoding due to their reduced cost, facile reading, robustness, and durability. For this, the use of fluorescent systems that combine multicolor emission with sensitivity to external stimuli will be highly desirable, as they can offer rewritable data encoding together with enhanced encryption security and storage density.

Phosphine ligands play a crucial role in homogeneous catalysis, allowing fine-tuning of the catalytic activity of various metals by modifying their structure. An ultimate challenge in this field is to reach controlled modulation of catalysis in situ, for which the development of phosphines capable of photoswitching between states with differential electronic properties has been proposed.
