“…[14][15][16][17][18][19][20][21][22][23] In recent times, fluorescent chemosensors have gradually become a pace-setter compared to other traditional analytical techniques (e.g., atomic emission spectrometry, neutron activation analysis, inductively coupled plasma spectrometry, mass spectrometry, Raman scattering, electrothermal atomic absorption spectrometry, atomic absorption spectrometry, and voltammetry) because of their advantages such as high sensitivity and selectivity, a low concentration of analyte, effective, economical, trouble-free process, and naked-eye detection. [24][25][26][27][28][29][30][31][32][33] However, the design of fluorescent chemosensor for the most common binding and signalling approach required some of the crucial chemical components, which are predominantly obtained based on supramolecular chemistry principles for specific recognition in different media. Basically, the construction of a chemosensor involves the fusion of three basic units.…”
