WebJul 1, 2012 · This study reported, for the first time systematically, photodegradation of Rhodamine B (RhB) in aqueous solution over BiOCl and BiOBr semiconductors. Under visible light irradiation (λ>400 nm, λ>420 nm and λ=550±15 nm), RhB adsorbed on the surface of BiOCl and BiOBr was photosensitized and decomposed effectively over unexcited BiOCl … WebJun 21, 2024 · Researchers have determined the mechanism by which one of the most popular families of organic dyes—the cyanines—shift their absorbance spectra to shorter wavelengths over time. This process, known as photoblueing, can confound experimental results. The new findings could help manipulate reaction conditions to avoid the process …

Webwidespread use of the cyanine scaffold, the chemistry underpinning this “photoblueing” artifact had remained opaque. We recently found that the irradiation of the simplest pentamethine cyanine, 2, leads to formation of the corresponding trimethine cyanine, 3 (Fig. 1b).13 This reaction, involving the formal excision of ethene diradical from ...
