A novel colorimetric detection probe for copper(II) ions based on a Schiff base

Rhodamine‐based Colorimetric and Fluorescent Chemosensors for the Detection of Cu2+ Ions and its Application to Bioimaging

“…Unfortunately, these methods involve high-priced equipment and include inefficient and arduous procedures that can only be performed by experienced experts. [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] Rhodamine 6G and B constitute another very significant class of metal sensors. As such, there has been a significant amount of resources devoted to design and development of novel fluorescence chemosensors to detect presence of metal ions.…”

A simple and facile colorimetric chemosensor for selective detection of Cu2+ ion in aqueous solution

“…Consequently, a large number of papers involving colorimetric chemosensor [18][19][20][21][22][23], fluorescent chemosensor [24][25][26][27][28][29] and other techniques [30][31][32][33][34][35] have been published for metal ion detection. In recent themed issue series of Chemical Society Reviews on sensor targets and imaging agents also confined an exciting mix of reviews focusing on small organic or transition metal receptors.…”

1-(1-Hydroxynaphthalen-2-Yl) Ethanone: Crystal Structure, Photo Physical Study and Turn OFF Molecular Switch with Cu (II) Ion

“…However, most of the methods are time-consuming and requires expensive instrumentation techniques [4][5][6][7][8][9]. Therefore, development of a selective, sensitive and easy method [10][11][12][13][14] to detect Cu 2+ ions becomes essential. Cu 2+ ion is a fluorescent quencher due to its paramagnetic nature and so a fluorescent receptor responds towards Cu 2+ ion can act as molecular switches [15][16][17].…”
