Journal ArticleDOI
Kinetics and mechanisms of chlorine dioxide oxidation of tryptophan.
TL;DR: The reactions of aqueous ClO2 and tryptophan (Trp) are investigated by stopped-flow kinetics, and the products are identified by high-performance liquid chromatography coupled with electrospray ionization mass spectrometry and by ion chromatography.
Journal ArticleDOI
An amide-linked chromophore-catalyst assembly for water oxidation.
Dennis L. Ashford,David J. Stewart,Christopher R. K. Glasson,Robert A. Binstead,Daniel P. Harrison,Michael R. Norris,Javier J. Concepcion,Zhen Fang,Joseph L. Templeton,Thomas J. Meyer +9 more
TL;DR: With the saturated methylene linker present, the individual properties of both the chromophore and catalyst are retained including water oxidation catalysis and relatively slow energy transfer from the Chromophore excited state to the catalyst.
Journal ArticleDOI
Exciplex formation in blended spin-cast films of fluorene-linked dyes and bisphthalimide quenchers.

TL;DR: Spin-cast films of dyes blended with nonconjugated bisphthalimides formed from nonlinked donors and acceptors in the solid state might have potential uses in nonlinear photonics.
Journal ArticleDOI
Chlorine Dioxide Oxidation of Guanosine 5‘-Monophosphate
TL;DR: The reactions between aqueous ClO2 and guanosine 5'-monophosphate (5'-GMP) are investigated from pH 5.96 to 8.30 to give oxidized products and Imidazolone and monochlorinated imidazlone are identified as products of the reaction between ClO 2 and Guanosine.
Journal ArticleDOI
Excited-state dynamics in rigid media: evidence for long-range energy transfer.
TL;DR: Evidence for triplet-triplet annihilation between triplet anthracene excited states in the films was obtained from the concentration dependences of excited-state decay, providing evidence for long-range energy migration between derivatized anthracenes in rigid, cross-linked PEG-DMA550 films.
