Rigidified malononitrile- and ketone-merocyanines in rigid environments

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2015
Two merocyanine dyes containing a malononitrile or a ketone functional group as electron-acceptors, and a piperidine group as electron-donor were synthetized and crystallized as pigments.

Investigating nano-structuring within imidazolium ionic liquids: A thermodynamic study using photochromic molecular probes [PDF]

open access: yes, 2009
Following previous studies involving the thermal relaxation of spirocyclic compounds we extended our studies to investigate the formation of nano-structured domains in ionic liquids (ILs).

Synthesis and characterisation of spiropyran-polymer brushes in micro-capillaries: towards an integrated optical sensor for continuous flow analysis [PDF]

open access: yes, 2011
Fused silica-capillaries were successfully functionalised with spiropyran-polymer brushes using spiropyran functionalised norbornyl derivative as monomer. The polymerisation was achieved by surface-initiated ring- opening metathesis polymerisation.

Recent advances in applications of merocyanine dye as sensitizers in solar cells

open access: yesNext Materials
Solar cells based on a dye as a sensitizer have compelling importance in the field of energy conversion. New developments in this rapidly expanding area are continuously appearing in literature based on dye as a sensitizer for the new type of solar cells

The dependence of the molecular first hyperpolarizabilities of merocyanines on ground-state polarization and length [PDF]

open access: yes, 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 ...

Differential interactions of bacterial lipopolysaccharides with lipid membranes: implications for TRPA1-mediated chemosensation

open access: yesScientific Reports, 2018
Bacterial lipopolysaccharides (LPS) activate the TRPA1 cation channels in sensory neurons, leading to acute pain and inflammation in mice and to aversive behaviors in fruit flies.

A novel fluorescent sensor protein for detecting changes in airway surface liquid glucose concentration. [PDF]

open access: yes, 2014
Both lung disease and elevation of blood glucose are associated with increased glucose concentration (from 0.4 to ~4.0 mM) in the airway surface liquid (ASL).

Reversible low-light induced photoswitching of crowned spiropyran-DO3A complexed with gadolinium(III) ions. [PDF]

open access: yes, 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

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches

open access: yesChemistry – A European Journal, EarlyView.
We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...
