A highly selective and sensitive fluorescent chemosensor for Zn²⁺based on a diarylethene derivative

Abstract

A promising photochromic fluorescent chemosensor1olinked with Schiff base unit was synthesized and the sensitivity test of1otoward Zn2+has been performed with detection limit up to 8.10 × 10−8M without any interference from Cd2+.

A novel diarylethene‐based fluorescence sensor with a benzohydrazide unit for the detection of Zn2+

“…The result is far below the acceptable limit (7.0 × 10 −6 mol L −1 ) in drinking water defined by WHO. Compared with those of Zn 2+ sensors reported previously, [ 40,69–78 ] the LOD was the lowest (Table 1), indicating that the sensor 1o for Zn 2+ was high sensitive.…”

A monomolecular platform with varying gated photochromism

“…As one type of logic devices, logic circuit with multiple input and output signals has been designed delicately and shows great potential in logic operations. [35][36][37][38][39] As mentioned above, varying degrees of gating photochromic properties were realized by the introduction of Cu 2+ and Ni 2+ to the methanol solution of compound DTEP. On this basis, a smart logic circuit (Fig.…”

A novel diarylethene-based fluorescent “turn-on” sensor for the selective detection of Mg2+

“…The isomerization of C]N bond was inhibited, which increased the rigidity of the molecule, resulting in the chelation enhanced uorescence (CHEF) effect. 73 The uorescence switching property of 1o 0 was also investigated. As shown in Fig.…”
