A new rhodamine based OFF–ON fluorescent chemosensors for selective detection of Hg2+ and Al3+ in aqueous media

Design and synthesis of a new rhodamine B-based fluorescent probe for selective detection of glutathione and its application for live cell imaging

“…[28][29][30] Among the fluorophores developed, rhodamine B and its derivatives are highly favorable as molecular probes in the study of complex biological systems because of their high absorption coefficients, high fluorescence quantum yields, long absorption and emission wavelengths and good cell-penetrating ability. [31][32][33][34] On the basis of the spirolactam/ring-opened amide equilibrium of rhodamine, several fluorescence-based sensing systems for metal ions have been developed to serve as a fluorescent chemosensor to detect metal ions, such as Hg 2+ , Cu 2+ , Al 3+ , Cr 3+ , Mg 2+ , and Fe 3+ . [35][36][37][38][39][40][41][42][43] However, to the best of our knowledge, rhodamine B-based fluorescent probes for GSH are still rare.…”

Radiative decay channel assessment to understand the sensing mechanism of a fluorescent turn‐on Al3+ chemosensor

“…more damage to impaired lung function and in the nervous system, causing Alzheimer's, amyotrophic lateral sclerosis, [7] or Parkinson's disease. [4,5,8] Therefore, the detection and monitoring of Al 3+ cations in samples of environmental and biological assays is of great interest, [3] which has inspired science and industry to implement diverse methods to accomplish these aims. [9] The analytical methods used the most are the spectroscopic and electrometric methods.…”

A highly sensitive and selective fluorescent probe for quantitative detection of Al3+ in food, water, and living cells

“…[13][14][15] In the past few years, many uorescent probes for Al 3+ detection have been reported. [16][17][18][19][20][21][22][23][24][25] However, there are still some shortcomings in reported Al 3+ uorescent probes, including a complex synthesis process, poor selectivity and sensitivity, easy interference by other metal ions, Zn 2+ , Cu 2+ , Cr 3+ , Hg 2+ , and even F À , [26][27][28][29][30] and lack of applicability to water samples and food samples. [31][32][33][34][35] Therefore, developing a uorescence probe with high sensitivity, good selectivity, rapid response and low toxicity for detecting Al 3+ is particularly meaningful.…”
