Photo-Modulated Proton Transport in Merocyanine Metastable-State Photoacid Based Polymers. [PDF]

Small
The covalent incorporation of merocyanine metastable‐state photoacid into soft polymers imparts conductivity to otherwise insulating matrices, allowing light‐triggered control of charge and structure, offering a new platform for photo‐responsive, ion‐conducting materials.

Reversible Low-Light Induced Photoswitching of Crowned Spiropyran-DO3A Complexed with Gadolinium(III) Ions [PDF]

Molecules, 2012
Photoswitchable spiropyran has been conjugated to the crowned ring system DO3A, which improves its solubility in dipolar and polar media and stabilizes the merocyanine isomer. Adding the lanthanide ion gadolinium(III) to the macrocyclic ring system leads

A merocyanine-based conductive polymer [PDF]

Journal of Materials Chemistry C, 2013
We report the first example of a conducting polymer with a merocyanine incorporated into the polymer backbone by electropolymerisation of a spiropyran moiety covalently linked between two alkoxythiophene units. Utilising the known metal coordination capabilities of merocyanines, introduction of cobalt ions into the electropolymerisation led to an ...

Merocyanine dyes [PDF]

Physical Sciences Reviews, 2021
Abstract Merocyanine dyes belong to the class of neutral polymethine dyes, where one terminal component is typically found in cyanine dyes and the second obtained from an active methylene compound. The different electron acceptor/donator abilities of the two terminal components have a marked impact on the electronic structure of a ...
