A new crystalline complex is successfully synthesized based on Dawson type polyoxometalate and amino substituted viologen. It exhibits ultrasensitive photochromic and Raman dual response to ethylenediamine gas.
A 3D silver(I)-polyoxometalate complex of Ag6[MnMo9O32]·4H2O was designed to realize the the elusive label-free SERS quantitative analysis for hydrazine, by which the ratiometric IMn-O/IMo-O signals are proportional to hydrazine concentrations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
