Electrochemically Induced Acidochromism at Poly‐Spiropyran‐Modified Electrodes
ChemPhotoChem, Volume 10, Issue 10, October 2026.Proton release at electrode interfaces sensed by spiropyran acidochromism. Spiropyrans are versatile photo‐ and acidochromes that also show reversible redox chemistry. The acidochromism of a spiropyran‐based redox polymer is shown here to provide a unique method to “read out” the large local changes in pH that can occur at electrodes during cyclic ...

Diarylethene-modified nucleotides for switching optical properties in DNA
Beilstein Journal of Organic Chemistry, 2012 Diarylethenes were attached to the 5-position of 2’-deoxyuridine in order to yield three different photochromic nucleosides. All nucleosides were characterized with respect to their absorption and photochromic properties. Based on these results, the most

Acceleration of photochromism and negative photochromism by the interactions with mesoporous silicas
Photochemical & Photobiological Sciences, 2019 The adsorption of merocyanine dye onto mesoporous silicas with varied pore sizes (5.5, 9.4 and 2.2 nm) from the toluene solution of 1,3,3-trimethylindolino-6'-nitrobenzopyrylospiran under UV irradiation was investigated quantitatively. The photoinduced adsorption of merocyanine onto SBA-15 with the pore diameter of 9.4 nm followed the pseudo-second ...
