A T-shaped triazatruxene probe for the naked-eye detection of HCl gas with high sensitivity and selectivity

Abstract

A T-shaped Schiff-base triazatruxene derivative (TATNFF) was designed, synthesized, and explored as a sensitive probe to detect HCl gas by the naked eye. The remarkable color change of TATNFF with turn-on behavior in the presence of a trace amount of HCl gas was obviously observed by the naked eye, which opens up a new strategy to explore a novel set of smart responsive materials for sensing applications.

Beryllium Complexes with Bio‐Relevant Functional Groups: Coordination Geometries and Binding Affinities

“…In situ reaction monitoring reveals an additional intense signal at 1.5 ppm which derives from HCl. [16] No further signals were observed, which leads to the conclusion that the benzoic acid is completely deprotonated. This finding is in agreement with the IR spectrum of compound 1 where no OÀHb and was observed.…”

Electrochemical Detection of Chloride Ions by Copper (II) Complex with Mixed Ligand of Oxindole Derivative and Dithiocarbamates Moiety

“…The heterocyclic organic ligand (L1) was synthesized by a single-step cyclization condensation reaction from oxindole in the presence of POCl 3 at reflux temperature [25]. The Cu (II) complex (Scheme 1) was synthesized using CuCl 2 •2H 2 O as the precursor and sodium diethyldithiocarbamate as a secondary ligand (L2).…”

Mechano-fluorochromic behavior of AEE polyurethane films and their high sensitivity to halogen acid gas

“…However, I À ion was too large to insert into the space between C]N and the benzene ring of the TABD. 46,47 Thus, I À ion reacted with TABD uorogen by electrostatic interactions and offered more diffusion channels for the excitons to migrate, allowing them to be more quickly annihilated by the hydrogen iodide. 48 Next, when these lms were fumed with ammonia gas, halogen ion could react with NH 4 + due to the acid-base neutralization.…”
