Ratiometric SERS detection of N2H4 by porous Ag(i)-linked Waugh-type polyoxometalate as an efficient label-free substrate

Abstract: 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.

“…Finally, the 2D layers expand into a three-dimensional structure through the coordination of polyoxoanions (Figure a), and the [MnMo 9 O 32 ] 6– anions are encapsulated in the channels of the 3D structure, beneficial to improving the stability of the compound. Such a 3D Ln-containing POMOF structure based on [MnMo 9 O 32 ] 6– anions is interesting and uncommon . Notably, it is precisely the high coordination number and strong oxygen affinity of Ln 3+ ions that promote the formation of the 3D structure.…”

“…Such a 3D Lncontaining POMOF structure based on [MnMo 9 O 32 ] 6− anions is interesting and uncommon. 62 Notably, it is precisely the high coordination number and strong oxygen affinity of Ln 3+ ions that promote the formation of the 3D structure. Furthermore, although the overall structure of compound 2 is racemic, the helix provides an effective method to construct a chiral framework and is significant for the chiral resolution of L-and R-[MnMo 9 O 32 ] 6− anions.…”

“…As a result, extremely sensitive methods are needed to monitor the increase in N 2 H 4 leakage into the ecosystem. To address this, several analytical methods such as flow injection, 23,24 electrochemical sensing, 25,26 titrimetric, 27,28 chromatography, 29,30 chemiluminescence, 31,32 and SERS-based detection 33 have been devised to reveal the trace amount of N 2 H 4 . Unfortunately, the majority of these techniques frequently demand laborious operations, prolonged processing times, and expensive equipment that makes biological imaging and real-time monitoring challenging.…”
