Disposable paper-based PET fluorescence probe linked with calix[4]arene for lithium and phosphate ion detection

Abstract

As a part of our ongoing efforts, we have synthesized a new fluorescence probe p-C4A based on calix[4]arene substituted by 4-aminoquinoline moieties with amide linkage, which can selectively recognize Li+...

Fabrication of para-dimethylamine calix[4]arene functionalized self-assembled graphene oxide composite material for effective removal of 2, 4, 6-tri-Cholorphenol from aqueous environment

“…But among them, calixarene is the third generation supramolecular host compound after the crown ethers and cyclodextrins [ 29 ]. However, calixarenes and their derivatives have unique complexation abilities that allow for recognition of target molecules with high selectivity and efficient supramolecular recognition as well [ 30 , 31 ]. Moreover, they contain numerous cavity dimension with possibility to functionalization their upper and lower rim with different functional groups to improve its properties and to tailor their strong interaction with a target host molecules through different non-covalent interaction such as hydrogen bonding, π - π stacking, cation- π and CH-π interaction with the surface of target molecule [ [32] , [33] , [34] ].…”

A review on photochemical sensors for lithium ion detection: relationship between the structure and performance

“…On the other hand, in the presence of Li + , the suppression of PET or in other words "PET-OFF" from aza-crown ether to NDI was occurred, which increased the uorescence emission. 93,115 Grabchev et al 116 synthesized a polyamidoamine dendrimer modied with 4-hexylamino-1,8-napthalimide as a uorescent and photochromic sensor for the detection of lithium ions. 117 In the alkaline media (in the presence of NaOH), deprotonation of the hexylamino groups at the C-4 position of the 1,8-naphthalimide structure was performed.…”

Construction of coumarin-appended calix[4]arene-based fluorescence sensor for the detection of carbofuran in cabbage

“…Our expertise in host-guest chemistry and uorescence sensors motivated us to explore novel synthetic uorescent host-guest systems for the purpose of detecting different molecular ions. [44][45][46][47][48][49][50][51][52] Following our seminal innovation of different receptors, we envisaged that substitution at the lowerrim of calix [4]arene with a cystamine linkage and coumarin uorophore will be a suitable approach for the recognition of CBF insecticide. This study proposes a scalable and extendable strategy for designing the highly efficient uorescence sensor CouC4S for the detection of CBF insecticide.…”
