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.

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 ...

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2017 The optical properties and dynamics of transport of electron excitation and the ways of its relaxation in the supramolecular D–π–A complex on the basis of merocyanines have been investigated. There have been found two components in the transfer of charge:

Designing naphthopyran mechanophores with tunable mechanochromic behavior. [PDF]
Chem Sci, 2020 Mechanochromic molecular force probes conveniently report on stress and strain in polymeric materials through straightforward visual cues. We capitalize on the versatility of the naphthopyran framework to design a series of mechanochromic mechanophores ...

Practical Broad-Band Tuning of Dye Lasers by Solvent Shifting [PDF]
, 1986 We have operated a dye laser over a broad wavelength range (593.8-667.0nm) by shifting the dye emission profile with incremental changes of solvent composition. This was accomplished with the laser operating continuously, and only minor adjustment of the

The dependence of the molecular first hyperpolarizabilities of merocyanines on ground-state polarization and length [PDF]
, 1994 We report here the dipole moment (µ) and first hyperpolarizability (β) determined by electric field-induced second harmonic generation, for several merocyanine dyes containing an 1,3,3-trimethylindoline heterocycle as a ‘donor’ in which the ‘acceptor ...

Photoannealing of Merocyanine Aggregates
The Journal of Physical Chemistry A, 2018 In this work we elucidate the fundamental difference between aggregate formation of donor-π-acceptor merocyanines in their electronic ground and excited states. While increasing the π-bridge size favors formation of π-stacked aggregates in the dark, irradiation with visible light causes reorientation of the dyes to form prototype H-aggregates with ...

Synthesis of Merocyanine Dyes [PDF]
Bulletin of the Chemical Society of Japan, 1978 Abstract New 1-ethyl-2-[(2-substituted 3-oxoisoindolin-1-ylidene)methyl]-pyridinium or quinolinium iodide merocyanine dyes were obtained by the reaction of 2-methyl quaternary salts with N-substituted phthalimide in the presence of piperidine.
