How explosive TNP interacts with a small tritopic receptor: a combined crystallographic and thermodynamic approach

Abstract

The interaction of explosive and pollutant TNP with the host receptor has been thoroughly explained and characterized by SCXRD and thermodynamic parameters.

Design and Development of Fluorescent Sensors with Mixed Aromatic Bicyclic Fused Rings and Pyridyl Groups: Solid Mediated Selective Detection of 2,4,6-Trinitrophenol in Water

“…The K sv values of 1 and 2 are greater than those of sensors containing fluorescein (3.94 × 10 4 and 2.10 × 10 4 M –1 ) 13a and naphthalene (2.69 × 10 4 and 3.43 × 10 3 M –1 ), 10a,13b whereas they are comparable to those of anthracene-tagged sensors (8.08 × 10 4 and 7 × 10 4 M –1 ). 10a,13c Also, the detection limit is greater than those with pyrene (2.98 ppm) 12 - and naphthalene (3.48 ppm) 13b -based sensors, respectively. The SV plots for TNP in both cases exhibit linearity at lower concentrations and an upward bent curve at higher concentrations.…”

A long-persistent phosphorescent chemosensor for the detection of TNP based on CaTiO3:Pr3+@SiO2 photoluminescence materials

“…Photoluminescence (PL)-based chemosensors have gained more attention because of their low instrumentation cost, short response time, high sensitivity and selectivity. 21,22 On the other hand, when using an optical sensing technology, a large background uorescence signal will cause a negative impact during detection process, 23,24 Compared with uorescent materials, phosphorescent materials can eliminate the interference from short-lived uorescent background by using time-resolved technology, with added advantages of high luminescence efficiency, and good photo and thermal stabilities. [25][26][27] Nevertheless, so far there are few reports about detecting nitroaromatic explosives by means of phosphorescence method.…”

Intracellular Fluorometric Recognition of Explosive and Mutagenic Nitroaromatics by a Luminescent Phenanthrene‐Naphthalene Sulfone

“…[2] To be more precise, when the emission mechanism is studied between Br-LANS and epNACs, the chances of resonance energy transfer (RET) has become prime matter of interest. [33][34][35] The absorption spectrum of NACs and emission spectrum of Br-LANS has a common overlapping zone where the maximum overlap is happening with TNP ( Figure 2). In solution, the guest TNP would obviously absorb the excited state energy of Br-LANS and quench the fluorescence.…”
