Morphology directing synthesis of 1-aminopyrene microstructures and its super quenching effect towards nitro aromatics

Mechanistic Insight into Selective Sensing of Hazardous Hg2+ and Explosive Picric Acid by Using a Pyrene‐Azine‐Hydroxyquinoline Framework in Differential Media

“…To further quantitatively analyze the quenching phenomena, the titration data is fitted with Stern-Volmer (SÀ V) equation as described in SI. [45,46] The linearly fitted SÀ V plot ( Figure S12) at lower concentrations of PA (0-50 μM) gives the value of K sv as 1.48 x 10 4 M À 1 (Figure 11d). The LOD is also calculated to be 55 nM for PA detection ( Figure S13).…”

Acid–base equilibrium in non-aqueous medium: colorimetric visualization, estimation of acidity constants and construction of molecular logic gates

“…To detect tiny quantities of acid-base in aqueous and non-aqueous media, a variety of acid-base sensors, including indicator reagents or strips, pH electrodes (hydrogen electrode, quinhydrone electrode, antimony electrode, glass electrode), and optical sensors, have recently arrived on the market. Among the different acid-base detectors, optical sensors [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] have drawn much interest because of their potential for efficiency, resistance to electrical curiosity, and capacity for unreachable sensing. However, it has been reported that several organic dyes can function as colorimetric sensors in non-aqueous solutions.…”

An Off‐On‐Off Benzoxazole‐Based Fluorosensor for Relay Detection of Al3+ Ions and Explosive Nitroaromatic Compounds

“…So, the detection of Al 3 + ions, fluorescent chemosensors have attracted significant attention due to their excellent selectivity, low cost, high sensitivity, on-site and real-time analysis, and also because of their huge application in various fields like analytical chemistry, medicinal biology, and the environmental sciences. [17][18][19][20][21][22][23][24][25][26][27] In the past few years, many fluorescence-based probes have been designed and synthesized, but due to strong hydration ability and relatively poor coordination, it is very challenging to develop an Al 3 + -specific fluorescence sensor. However, some researchers have effectively synthesized a limited number of very sensitive and selective Al 3 + ions fluorescence sensors and overwhelm the complications associated with the selectivity of detecting minute levels of Al 3 + ions over other ions.…”

“…Again due to a lack of d orbital, it is unable to perform spectrometric analysis. So, the detection of Al 3+ ions, fluorescent chemosensors have attracted significant attention due to their excellent selectivity, low cost, high sensitivity, on‐site and real‐time analysis, and also because of their huge application in various fields like analytical chemistry, medicinal biology, and the environmental sciences [17–27] …”
