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

Chemistry – 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 ...

Synthesis and metal binding properties of N-alkylcarboxyspiropyrans

Beilstein Journal of Organic Chemistry, 2017
Spiropyrans bearing an N-alkylcarboxylate tether are a common structure in dynamic, photoactive materials and serve as colourimetric/fluorimetric cation receptors.

E–Z Photoisomerization in Proton-Modulated Photoswitchable Merocyanine Based on Benzothiazolium and o-Hydroxynaphthalene Platform

Photochem, 2023
The potential of E–Z photoisomerization in molecular organic light-to-thermal conversion and storage in an E–styryl merocyanine system was studied in a polar acidic medium. A photoswitchable styryl merocyanine dye (E)-2-(2-(2-hydroxynaphthalen-1-yl)vinyl)

Neue Versuche mit Spiropyran: Photometrie, NMR‐Spektroskopie und On‐Water‐Synthese

CHEMKON, EarlyView.
Reaktionskinetik wird häufig als schwierig, theoretisch und Mathematik‐lastig empfunden, weshalb experimentelle Zugänge für diesem Themenbereich notwendig sind. In diesem Beitrag werden entsprechende Versuche zur Reaktionskinetik vorgestellt, bei denen das Farbstoffsystem eines Spiropyrans und dessen isomerer Merocyanin‐Form untersucht wird.

Spiropyran polymeric microcapillary coatings for photodetection of solvent polarity [PDF]

, 2013
Fused silica micro-capillaries were functionalised with spiropyran-polymer brushes using surface-initiated ring-opening metathesis polymerisation. Based on the inherited spiropyran properties, the functionalised capillaries were successfully used to ...

Spiropyran-Modified Cellulose for Dual Solvent and Acid/Base Vapor Sensing

Chemosensors
Stimuli-responsive materials based on renewable biopolymers are highly attractive for developing sustainable chemical sensors. Here, two spiropyran derivatives (SP1 and SP2) were synthesized and covalently grafted onto cellulose, yielding the functional ...

Electrochromic properties of spiropyran-terthiophene adaptive polymers [PDF]

, 2010
Adaptive materials have the ability to modify their behaviour or characteristics in response to external stimuli, for example through electrochemical changes, macroscopically in the molecular structure. These materials may have only one form with binding
