Abstract

Abstract : The Back Cover picture shows a new strategy for SERS‐based quantification of inorganic mercury (Hg II ) in water. Design and synthesis from azathioethers (DMA and TTM) to an azathiacrown [7‐aza‐1, 4, 10, 13‐tetrathiacyclohexadecane (NS4)] demonstrate an improved S‐pulling effect and size‐fit specificity towards Hg II to form Hg‐S bonds. Modification of NS4 on the surface of Au@SiO2 by using a 4‐(bromomethyl) benzoic linker enables direct SERS‐based specific quantification of Hg II, in which phenyl serves as an internal standard (IS). More information can be found in the Communication by Q. Wang and co‐workers onpage 201 in Issue 2, 2017 (DOI:10.1002/open.201600135 ).
