Effects of Ultra High Dilution of Paraquat 30 cH on Growth, Chlorophyll Content and Yield of Rice Crop
The application of synthetic fertilizers reduces the natural fertility of the soil and contaminates groundwater. Some photosynthesis inhibitors at ultra-high dilution (UHD) increase photosynthesis,…

The Early Years of 2,2′-Bipyridine—A Ligand in Its Own Lifetime
The first fifty years of the chemistry of 2,2′-bipyridine are reviewed from its first discovery in 1888 to the outbreak of the second global conflict in 1939. The coordination chemistry and…

Environmental fate and ecotoxicology of paraquat: a California perspective
- ChemistryToxicological & Environmental Chemistry
ABSTRACT The herbicide paraquat belongs to the group of the bipyridylium salts. In California, it is used primarily for control of broad-leaved grasses in fruit orchards and plantations, as a cotton…

The photoelectrochemical studies indicate that the as-obtained hybrid displays a p-type semiconductor behavior under visible-light illumination.
Well-defined polymers containing a single mid-chain viologen group: synthesis, environment-sensitive fluorescence, and redox activity
A difunctional viologen-based alkyl halide initiator was synthesized and used to initiate the copper-mediated atom transfer radical polymerization (ATRP) of methyl methacrylate to afford well-defined…
Synthesis, Structure, and Photochemical Behavior of Heli-viologen Isomers.
- ChemistryThe Journal of organic chemistry
The syntheses of isomeric helical viologens that have potential applications in supramolecular chemistry and catalysis have been developed and computational studies demonstrate that the magnitude of their racemization barriers is primarily determined by the identity of the helical scaffold and is insensitive to the placement of the viologen functional group.
