A piezogravimetric sensor platform for sensitive detection of lead (II) ions in water based on calix[4]resorcinarene macrocycles: Synthesis, characterization and detection

Calix[4]Resorcinarene Macrocycles Interactions with Cd2+, Hg2+, Pb2+, and Cu2+ Cations: A QCM‐I and Langmuir Ultra‐thin Monolayers Study

“…Both ionophores ( I ) and ( II ) were prepared from C‐dec‐9‐en‐1‐ylcalix[4]resorcinarene ( A ) and are structurally and chemically characterized in earlier work .…”

“…The usage of sensors and ion selective electrodes as alternative for the HM control and detection is vastly explored. The advantages of applying these techniques rely on the possibility of detection surface modification with selective sensing platforms such as DNA probes, proteins, nanostructures, and macrocycles .…”

“…Macrocycles sensing networks have a subtype manifests in calixarenes and calixresorcinarenes, which are considered as third‐generation macrocyclic compounds after crown‐ethers and cyclodextrines. Due to their amphiphilic and host‐guest properties towards cations, anions, and neutral molecules, they were immensely employed in sensing and recognition applications .…”

Fabrication of Hybrid Electrodes by Laser-Induced Forward Transfer for the Detection of Cu2+ Ions

“…Heavy metal trace detection is mainly carried out using spectroscopic techniques: atomic absorption spectroscopy [ 8 ], inductively coupled plasma mass spectroscopy [ 9 ], X-ray fluorescence, quartz crystal microbalance [ 10 ], and neutron activation analysis are the most commonly used. However, they suffer from several significant drawbacks, including tedious sample preparation, the need for expert knowledge, high operational costs, and lengthy analysis time (calibration, pre-concentration, preparation, sampling) [ 11 ], which make them unsuitable for real-time online and continuous monitoring applications. On the contrary, biosensors [ 12 ] based on electrochemical devices represent an attractive alternative due to their numerous advantages.…”

Removal of Toxic Metal Ions Using Poly(BuMA–co–EDMA) Modified with C-Tetra(nonyl)calix[4]resorcinarene

“…Calix[4]resorcinarenes, commonly known as resorcinarenes, are obtained from the condensation reaction of resorcinol with different aldehydes in acid solutions [ 12 , 13 ], and they can be modified with various substituents on their upper rim in order to provide specific functionality and selectivity [ 14 , 15 , 16 ]. Calix[4]resorcinarenes have been widely used in numerous applications, such as sensors [ 17 , 18 ], catalysis [ 19 ], dendrimer synthesis [ 20 , 21 ], dyeing of fibers [ 22 , 23 ], NMR solvating agents [ 24 , 25 ], heavy metal complexes for water purification [ 26 , 27 ], and chemical separations by modification of multiple surface types [ 28 , 29 ].…”
