Micro-Capillary Coatings Based on Spiropyran Polymeric Brushes for Metal Ion Binding, Detection, and Release in Continuous Flow

Sensors, 2018
Micro-capillaries, capable of light-regulated binding and qualitative detection of divalent metal ions in continuous flow, have been realised through functionalisation with spiropyran photochromic brush-type coatings.

Substituent Effects Control Spiropyran-Merocyanine Equilibria and Mechanochromic Utility.

Macromolecular rapid communications, 2020
Spiropyran (SP) derivatives can be converted into the colored merocyanine (MC) form using a variety of triggers. Optical switching by light for memories and dynamic systems is long known.

Stepwise Folding and Self-Assembly of a Merocyanine Folda-Pentamer.

Journal of the American Chemical Society, 2020
Here we report a synthetic protocol toward a merocyanine (MC) pentamer 1 which represents the first merocyanine oligomer longer than dimer. By continuously decreasing the solvent polarity we demonstrate the stepwise folding from partially folded ...
