Molecular switch controlled by pulsed bias voltages

, 2009
It was observed in recent experiments that the current-voltage characteristics (IV) of BPDN-DT (bipyridyl- dinitro- oligophenylene- ethynylene- dithiol) can be switched in a very controlled manner between "on" and "off" traces by applying a pulse in a ...

Extracytoplasmic Function σ Factors Can Be Implemented as Robust Heterologous Genetic Switches in Bacillus subtilis

iScience, 2019
Summary: In bacteria, the promoter specificity of RNA polymerase is determined by interchangeable σ subunits. Extracytoplasmic function σ factors (ECFs) form the largest and most diverse family of alternative σ factors, and their suitability for ...

Nonlinear Optical Molecular Switches for Alkali Ion Identification

Molecules, 2014
This work demonstrates by means of DFT and ab initio calculations that recognition of alkali cations can be achieved by probing the variations of the second-order nonlinear optical properties along the commutation process in spiropyran/merocyanine ...

London dispersion as important factor for the stabilization of (Z)-azobenzenes in the presence of hydrogen bonding

Beilstein Journal of Organic Chemistry, 2018
The understanding and control of the light-induced isomerization of azobenzenes as one of the most important classes of molecular switches is crucial for the design of light-responsive materials using this entity.

A bisazobenzene crosslinker that isomerizes with visible light

Beilstein Journal of Organic Chemistry, 2012
Background: Large conformational and functional changes of azobenzene-modified biomolecules require longer azobenzene derivatives that undergo large end-to-end distance changes upon photoisomerization.
