A ratiometric, near-infrared, and fully water-soluble probe, a phenoxazinium-based chemosensor bearing an anilino thiaazacrown, was successfully synthesized and characterized. The use of this probe for the selective ratiometric detection of Hg2+ in pure water is reported. The probe shows good selectivity for Hg2+, and a large blue shift (75 nm) of the complex's absorption maximum was observed. (C) 2011 Elsevier Ltd. All rights reserved.
