TL;DR: A selective and sensitive fluorescent chemosensor for Hg2+, which was composed of two aminonaphthalimide fluorophores and a receptor of 2,6-bis(aminomethyl)pyridine, showed an about 17-fold increase in fluorescence quantum yield upon addition of 1 equiv of HG2+ in neutral buffer aqueous solution.

TL;DR: In this article, two novel fluorosensors of 4,5-disubstituted-N-alkyl-l,8-naphthalimide derivatives (H1, H2, H3) with double ethylenediamino receptors and one methylpiperazine receptor were synthesized, respectively.

TL;DR: The AQZ family members were highly soluble in water and showed good selectivity for Zn(2+)via enhanced fluorescence in aqueous buffer solution and Fluorescence signals could be tuned from dual-wavelength ratiometric changes to changes in the intensity of a single wavelength upon binding Zn (2+) through the introduction of different substituents onto the quinoline ring.

TL;DR: In this article, a novel hydroperoxide of benzothioxanthene dicarboximide B4 was synthesized through naphthyl radical-induced aromatic 1,5-hydrogen transfer in an unusual Pschorr cyclization and photooxygenation.

TL;DR: The developed chemosensor H1 exhibited good turn-on and reversible responses toward Hg2+, with excellent selectivity and sensitivity, in a neutral buffered aqueous solution, and showed a rapid and linear response toward H g2+ in the concentration range 0–10 μM.
