A rhodamine based chemodosimeter for the detection of Group 13 metal ions

Abstract

A new rhodamine derivative, HL-CIN, derived from a reaction between N-(rhodamine-6G)lactam-ethylenediamine (L1) and trans-cinnamaldehyde, is reported here for the colorimetric and fluorogenic sensing of Group 13 trivalent cations, namely Al3+,...

Detection of the +3 Oxidation State of Metal Ions with the Aid of a Rhodamine‐Based Dye and Applications in Construction of Complex Logic Circuits and Living Cell Imaging

“…Few aspects of recently published rhodamine based chemosensors [9,10b,12a,d,17,27–40] for different metal ions have been compared with HL‐qui (Table S6). In most of the cases, excitation wavelength is about 500 nm whereas the emission is observed at 550 or ~580 nm.…”

“…Recently, we have reported rhodamine derivatives for the sensing of trivalent metal ions of Group 13. [16,17] However, these probes could not identify Cr 3 + and Fe 3 + . There are other trivalent cations that need more attention.…”

“…However, these research articles concern about detection of Al 3+ , Cr 3+ and Fe 3+ as the only trivalent cations although there are other trivalent cations. Recently, we have reported rhodamine derivatives for the sensing of trivalent metal ions of Group 13 [16,17] . However, these probes could not identify Cr 3+ and Fe 3+ .…”

Imaging of Al3+in plant roots by the interaction with a bisphenol A-based chemosensor

“…There are several chemosensors for Al 3+ in the literature. 11,13,[44][45][46][47][48][49][50][51][52][53][54][55] Some parameters of recently published chemosensors for Al 3+ are summarized in Table 1. Most of them have been synthesized by Schiff-base condensation reactions (exception: entry 5).…”

Structure–metal ion selectivity of rhodamine-based chemosensors

“…Our group very recently reported a chemodosimeter ( 110 ) (Scheme 20) which was constructed from a reaction between N -(rhodamine-6G)lactam-ethylenediamine and trans -cinnamaldehyde. 127 It underwent hydrolysis in the presence of Group 13 cations, namely, Al 3+ , Ga 3+ , In 3+ and Tl 3+ in HEPES buffer in H 2 O/ethanol = 1 : 9 (v/v; pH = 7.4) to give a pink color and strong fluorescence at 558 nm. Hydrolyzed products were a spirocyclic ring opened species, which was responsible for the color change and strong fluorescence, and cinnamaldehyde.…”
