Abstract
Hugo Schiff (1864) created Schiff-bases by condensing primary amines with carbonyl compounds (ketone or aldehyde). Schiff-bases are used in many fields, including optoelectronics (metal ion sensing, explosive detection, aggregation induced emission (AIE), bioimaging) and medicine, due to their diverse structural and electrical properties. Schiff bases that coordinate with various metal ions produce a stable compound. Schiff bases are used as fluorescent turn-on/turn-off, colorimetric and ratiometric chemosensors because of their remarkable coordination ability, these chemosensors are used to identify different metal cations in samples, including Al3+, Cu2+, Sn2+, Cd2+, Hg2+, Ni2+, Zn2+, Hg2+, Fe3+, and Cr3+. This review article covers a wide range of Schiff bases used in chemosensing applications for various metal ions in aqueous medium and also in AIE-active fluorescent molecules, Moreover, this review includes good quality papers of last two decades.
期刊介绍:
Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied.
Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media.
The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
