Photochemical Switching of Electrochemical Process by Spiropyran LB Films
Authors: Nishiyama Katsuhiko , Fujihira Masamichi 
Published: July 2006

Abstract
Photoelectrochemical control of the ion-blocking ability of the Langmuir–Blodgett (LB) film as an ion gate was demonstrated on a gold optically semi-transparent electrode (Au OTE) coated with multilayers containing photoresponsive amphiphilic compounds. When UV light was irradiated upon the modified Au OTE, this LB film became more compact to block permeation of ions into and out of the LB film and therefore inhibited electrochemical reactions of the redox active species in solution. On the other hand, when visible light was irradiated, this layer became more loose and redox species could penetrate the LB film.

Abstract
The occurrence of the spinnability in the sols prepared by the hydrolysis and polycondensation of tetramethoxysilane, tetraethoxysilane, tetraisopropoxysilane and tetranormalbutoxysilane has been investigated.

It has also been shown that the spinnable solutions show the Newtonian behavior at high viscosities.
