A new off–on chemosensor for Al3+ and Cu2+ in two different systems based on a rhodamine B derivative

Addressing of multiple-metal ions on a single platform

“…Another rhodamine B derivative 31 had been reported by Chen et al [60] which acted as a double sensor for Al 3+ and Cu 2+ ions. The probe displayed selectivity for both the metal ions in different solvent systems.…”

A highly selective fluorescent chemosensor for Cu2+: synthesis and properties of a rhodamine B‐containing diarylethene

“…To demonstrate the real application of 1o , Cu 2 + in real water samples from Ganjiang River, Nanchang City were determined according to the reported methods . Different amounts of Cu 2 + were spiked into the real water samples.…”

Bis-Schiff base as a donor–acceptor fluorescent probe: Recognition of Al3+ ions in near 100% aqueous solution

“…Additionally, According to a WHO report, the average daily human intake of aluminum is around 3-10 mg. Tolerable weekly aluminum dietary intake in the human body is estimated to be 7mg / kg body weight [15][16]. In order to protect the environment and human health, it is crucial to develop an effective fluorescent probe for detection of the concentration levels of aluminum in the environment [17][18][19][20].…”
