A novel isophorone-based fluorescent probe for recognition of Al3+ and its bioimaging in cells and plants

A novel “turn on” fluorescence probe based on a caffeic acid skeleton for detecting Al3+ and bioimaging application

“…S9 †). 1 H NMR spectra depicted that aer adding Al 3+ , the proton signal at 8.45 ppm (NH, H a ) was weakened and that at 4.65 ppm (CH, H b ) remainedand shied to 5.62 ppm. These results indicated that the 1 : 1 complex of HAM with Al 3+ forms through the protons in the carbonyl and hydroxyl groups.…”

“…The uorescence data were collected using a Hitachi F-7100 spectrometer. 1 H NMR and 13 C NMR spectra of new compounds were obtained using AVANCE NEO 500 equipment. UV-vis absorption data were collected using a Hitachi UH5300 spectrometer.…”

“…A yellow product was obtained aer removing the solvent, which was puried by column chromatography (PE/EA = 3/1) to yield the product as yellow solid (175 mg, 92.3%). 1…”

“…Aluminium (Al) is one of the most abundant elements in the Earth's crust and plays a crucial role in many elds, such as papermaking, textiles, medicine, food additives, water purication systems, and construction materials. [1][2][3] Although aluminium is widely applied in many elds, from manufacturing industries to daily life, an excess of aluminium can cause harm to ecological, environmental and human health. For example, the accumulation of excess Al 3+ in soils can hinder the growth of plants.…”

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

“…40,41 Plant root imaging with H 4 L Currently, only a small number of studies have utilized chemosensors for imaging plant tissues; most of the studies use them for imaging living cells. 42,43 It is extremely important to identify Al 3+ ions in plant roots to understand the retarded growth because of the presence of this cation. Thus, the imaging of plant tissues with bisphenol derivatives has been investigated in order to detect Al 3+ in the root of rice seedlings.…”
