Photoinduced electron transfer quenching and sugar effects on the electrostatic interaction between an anionic Ru(II) complex and cationic bipyridinium derivatives functionalized with boronic acids was written by Uddin, Jamal Md.;DiCesare, Nicolas;Lakowicz, Joseph R.. And the article was included in Inorganica Chimica Acta in 2012.Formula: C12H16BBrO2 This article mentions the following:
The photoinduced electron transfer quenching of an anionic ruthenium(II) metal-ligand-complex (Ru(dpp(SO3Na)))2(mcbpy)Cl2 by two boronic acid functionalized benzyl viologen (BV2+) derivatives has been investigated as well as their response to sugar. The electrostatic interaction between these two charge species lead to the formation of static quenching which is removed in presence of sugar due to the formation of a neutral zwitterionic quencher. Spectral data, quenching parameters and sugar titration curves are presented and discussed in term of future developments of optical sensors for sugar. In the experiment, the researchers used many compounds, for example, 2-(2-(Bromomethyl)phenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 166821-88-1Formula: C12H16BBrO2).
2-(2-(Bromomethyl)phenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 166821-88-1) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Formula: C12H16BBrO2
