A new “turn-on” molecular switch for idiosyncratic detection of Al³⁺ ion along with its application in live cell imaging

Abstract

A highly sensitive, reversible, reusable and fluorogenic “turn-on” probe (HBTC) is fabricated for the sole detection of Al3+. On incremental addition of Al3+ in the solution of HBTC in ACN:H2O...

An ICT-based organic framework for the fluorogenic detection of lethal pulmonary agent phosgene

“…The synthetic design of BPCI is shown in (Scheme 1) where compounds 'a' and 'b' were prepared using our previously reported procedure. 62,63 Then, 4-hydroxy-[1,1 0 -biphenyl]-3-carbaldehyde (a) was reacted with 2-(1H-benzo[d]imidazol-2-yl) acetonitrile (b) in the presence of piperidine in ethanol medium, which yielded our desired probe (BPCI). Furthermore, the BPCI probe was thoroughly characterized by elemental analysis, 1 H NMR, 13 C NMR, IR, and HRMS spectroscopic methods, and the data are given in the ESI † (Fig.…”

A biphenyl thiosemicarbazide based fluorogenic chemosensor for selective recognition of Cd2+: application in cell bioimaging

“…This was prepared according to a previously reported procedure. 58 Synthesis of the probe (E)-2-((4-hydroxy-[1,1 ′ -biphenyl]-3-yl) methylene)-N-methylhydrazine-1-carbothioamide (HBMC)…”

Facile synthesis of a fluorescent probe based on a terbium-based metal–organic framework for selective detection of Fe(iii) and Al(iii)

“…11,12 Most seriously, Al 3+ is extremely harmful to the human body, increasing the risk of Parkinson's disease, breast cancer and Alzheimer's disease. [13][14][15] Therefore, it is imperative to develop a sensitive and robust analytical method to detect the concentrations of Fe 3+ and Al 3+ .…”
