Reversible Photoreduction as a Trigger for Photoresponsive Gels [PDF]

, 2016
We present here a new type of photoresponsive, reversible low molecular weight gel. All previous examples rely on a photoisomerisation, ring-closing or dimerization. We show that photoreduction of a perylene bisimide gelator results in the formation of a

Recovery of the Rod Photoresponse in Infants

Investigative Opthalmology & Visual Science, 2005
To study deactivation of the rod photoresponse in infants using a paired-flash procedure. Rhodopsin content increases and scales the parameters of the activation of rod phototransduction as rods develop. However, little is known about the kinetics of deactivation in the rods of young infants.ERG responses to pairs of flashes were used to study the ...

Terahertz photoresponse of black phosphorus

Optics Express, 2017
Two-dimensional black phosphorus is a new material that has gained widespread interest as an active material for optoelectronic applications. It features high carrier mobility that allows for efficient free-carrier absorption of terahertz radiation, even though the photon energy is far below the bandgap energy.

Photoresponsive Dioxazaborocanes‐Containing Oligomers

Chemistry – A European Journal
AbstractThe synthetic methodology for the preparation of photoresponsive dioxazaborocanes‐containing oligomers is developed. It relies on the transformation of the (diisopropylamino)boryl group (−BH(NiPr2)) into a dioxazaborocane unit in the presence of β‐aminodiols and involves a bis‐borylated dithienylethene photochromic unit.

Dynamic Surface Tension Behaviour in a Photoresponsive Surfactant System [PDF]

, 2006
We report on the surface properties of a photoresponsive surfactant that incorporates the light-sensitive azobenzene group into its tail. Cis-trans photo-isomerization of this group alters the ability of the surfactant to pack into adsorbed monolayers at

Recent Advances in Amphiphilic Photoresponsive Polymers: Toward Their Potential Use in Controlled Release Fertilizer

Macromolecular Materials and Engineering
Photoresponsive polymers have emerged as a dynamic class of materials exhibiting a response to light. On the other hand, amphiphilic polymers are materials possessing both hydrophobic and hydrophilic sides in their macromolecular structure.
