Pyridoxal-based low molecular weight progelator as a new chemosensor for the recognition of Ag⁺ and Hg²⁺ under different conditions

Abstract

Pro-gelator 1 shows visual detection of Ag+ ion through sol-to-gel conversion. Additionally, it exhibits the selective sensing of Hg2+ ion over a series of metal ions in solution.

Small‐Molecule Fluorescent Probe: Ratiometric and Selective Detection of Sodium Ions for Imaging and Solid‐State Sensing Applications

“…Pyridoxal based probes were successfully applied to various analytes. [47][48][49][50][51][52][53][54][55][56] We have recently reported the selective turn-on fluorescence sensing of Zn(II) by pyridoxal based probe. [57] Synthesis of the novel pyridoxal based sodium(I) complex (NaL) with water coordination was performed by treating the L with sodium acetate (Scheme 2).…”

A new pyridoxal-derived gelator for selective recognition of CN− and F− under different conditions

“…[23][24][25][26][27][28][29] In regard to this, the use of soft gel is limited, especially low molecular gelators (LMWGs) for CNion. 30 During our ongoing work on developing stimuli-responsive gelator cum chemical sensor, 8,31 we desire to disclose here a pyridoxal-based new gelator 1 for selective detection of CN - and Fions under different conditions (Figure 1). The compound 1 forms strong yellow gel in DMF:H 2 O (10:1, v/v) which undergoes gel-to-sol transformation with color change in presence of CN -.…”

“…Importantly, anion interaction features of pyridoxal-based supramolecular gelators in both gel and solution phases are not known in the literature except a few from our laboratory. 6–8…”

Bis-Pyridine-Based Organogel with AIE Effect and Sensing Performance towards Hg2+

“…Mercury enriched in fish and shrimp may enter the human body through the food chain and cause diseases including brain damage and chronic disease [ 47 , 48 ]. Many methods and materials have been used for the detection of mercury ions [ 49 , 50 , 51 , 52 , 53 , 54 ]. Therefore, there is a great demand to develop a simple, rapid and highly selective sensor for mercury ions.…”
