Spiropyran modified micro-fluidic chip channels as photonically controlled self-indicating system for metal ion accumulation and release [PDF]

, 2009
In this paper, we show how through integrating the beneficial characteristics of micro-fluidic devices and spiropyrans dyes, a simple and very innovative chip configured as an on-line photonically controlled self-indicating system for metal ion ...

Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

Advanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Hemiphosphoindigos as a platform for chiroptical or water soluble photoswitching

Nature Communications
Photoswitches are important molecular tools to precisely control the behavior of matter by using light irradiation. They have found application in virtually all applied chemical fields from chemical biology to material sciences. However, great challenges

On–off conduction photoswitching in modelled spiropyran-based metal-organic frameworks

Communications Chemistry, 2023
Materials with photoswitchable electronic properties and conductance values that can be reversibly changed over many orders of magnitude are highly desirable.

Photoswitchable basicity through the use of azoheteroarenes

, 2016
We report an azoheteroarene photoswitchable base, where proton stabilisation in Z isomer is facilitated by neighbouring imidazole rings. A 1.3 unit difference in pKa is observed between the E and Z isomers, which leads to the ability to reversibly ...

Photoswitching Conduction in Framework Materials

Advanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Water‐Soluble Arylazoisoxazole Photoswitches

Chemistry – A European Journal, 2023
AbstractAzoheteroarenes are emerging as powerful alternatives to azobenzene molecular photoswitches. In this study, water‐soluble arylazoisoxazole photoswitches are introduced. UV/vis and NMR spectroscopy revealed moderate to very good photostationary states and reversible photoisomerization between the E‐ and Z‐isomers over multiple cycles with ...

An All-Photonic Molecule-Based Parity Generator/Checker for Error Detection in Data Transmission [PDF]

, 2013
The function of a parity generator/checker, which is an essential operation for detecting errors in data transmission, has been realized with multiphotochromic switches by taking advantage of a neuron-like fluorescence response and reversible light ...
