A single fluorescent chemosensor for multiple target ions: Recognition of Zn2+ in 100% aqueous solution and F− in organic solvent

Zinc(II) and pyrophosphate selective fluorescence probe and its application to living cell imaging

“…Disorders in Zn 2+ metabolism have been connected to several neurological diseases, including Alzheimer's disease (AD) [4,5], cerebral ischemia [6], and epilepsy [7]. Therefore, the development of techniques for Zn 2+ detection in biological processes has been an important research topic [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”

Detection of multiple analytes (CN− and F−) based on a simple pyrazine-derived chemosensor in aqueous solution: Experimental and theoretical approaches

“…This bathochromic shift of the absorption band led us to propose the change of intramolecular charge transfer (ICT) band through the deprotonation of 1 by fluoride. The negative charge of 1 −1 generated from the deprotonation of the naphtholic proton of 1 by F − would lead to the red shift, resulting in the orange color [18]. To further confirm the sensing mechanism between 1 and F − , the interaction between 1 and OH − was also investigated (Fig.…”

The potential of ion mobility mass spectrometry for tuning synthetic host guest systems: A case study using novel zinc(II)dipicolylamine anion sensors

“…There has been a great deal of interest in the generation of selective anion sensors for use in aqueous environments [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49], or which could be used directly upon biological samples; however this is a challenge due to the high hydration energies of the ions. The large size of the phosphate anion along with its high hydrophilicity, place it near the bottom of the Hofmeister selectivity series [50].…”
