Photoinduced hydride transfer reaction between methylene blue and leuco crystal violet

Ultratrace Kinetic Measurements of the Reduction of Methylene Blue

“…3 MB + is known to accept a hydride in either a concerted or stepwise manner depending on the reaction partner and conditions. 4 Previous work has shown that the kinetics for reduction in water containing ascorbic acid is first order in each reagent. 5,6 We report the second-order reduction of methylene blue to leucomethylene blue (MBH) by ascorbic acid (H 2 A) in acetonitrile:…”

Solar light-driven reduction of crystal violet by a composite of g-C3N4, β-Ag2Se, γ-Fe2O3 and graphite

“…However, LCV is known to behave as an electron donor to semiconductors such as fullerenes (C60) [32], i.e., it is able to transfer hydrogen and electrons to suitable semiconductors. In fact, it has already been studied for hydride transfer to reduce methylene blue in reactions activated by UV and visible light [33]. Therefore, it cannot be excluded that the reaction in Eq.…”

A Benchmark Study on the Properties of Unsubstituted and Some Substituted Polypyrroles

“…As seen in Table 5, the bands signed at 235.05, 276.55, 317.70, 345.36, and 376.51 (nm) corresponds to the HOMO-LUMO transition and is of ICT (intramolecular charge transfer) character thus possessing higher transition intensity. Also it is has been established that organic molecules (including biological molecules and conjugated molecules) have a strong triplet-triplet transition [38,39]. For two, three, four and five rings MPC the singlet-singlet transition basically involves four (|H>, |H-1>, |L>and |L+1>) but preliminary calculations of spectra show an increase of the transition levels which can be used to orient the molecule and enable electron transfer.…”
