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.

By enabling rapid, cost-effective, user-friendly and in situ detection of carbon dioxide, colorimetric CO2 sensors are of relevance for a variety of fields. However, it still remains a challenge the development of optical chemosensors for CO2 that combine high sensitivity, selectivity and reusability with facile integration into solid materials. [...]

In the development of colorimetric biosensors, the use of electrochromic mediators has been accepted and widely used during decades. The main drawback of these types of enzymatic substrates is the difficult recovery of the initial redox state of the molecule, which can be done electrochemically or by antioxidants addition, complicating the initially simple structure of the biosensor.

Study of P(VDF-co-HFP)-ionic liquid based ionogels for designing flexible displays

Guirado López, Gonzalo (Universitat Autònoma de Barcelona. Departament de Química)
In flexible displays, solid electrolytes promote electron-transfer without compromising system integrity. Ionogels (IGs) are now preferred among other solid electrolytes, e. g. inorganic and hydrogel electrolytes, for being easier to produce than the former and showing excellent properties, including high ionic conductivities, broad electrochemical window, transparency, flexibility, and non-solvent volatility than the latter.
