“…When chemosensors respond to external stimuli, distinct and significant changes can be observed-for example, in color or fluorescence [4][5][6]. Anions are crucial in biological and environmental systems; optimum concentrations are critical to proper functioning, as an excess or diminished amount of anions can prove fatal in both systems [7].…”

Detailed Nuclear Magnetic Resonance (NMR) spectroscopy investigations on a novel naphthalene-substituted 1,2,3-triazole-based fluorescence sensor provided evidence for the "turn-on" detection of anions. The one-step, facile synthesis of the sensors was implemented using the "Click chemistry" approach in good yield. When investigated for selectivity and sensitivity against a series of anions (F − , Cl − , Br − , I − , H 2 PO 4 − , ClO 4 − , OAc − , and BF 4 − ), the sensor displayed the strongest fluorometric response for the fluoride anion. NMR and fluorescence spectroscopic studies validate a 1:1 binding stoichiometry between the sensor and the fluoride anion. Single crystal X-ray diffraction evidence revealed the structure of the sensor in the solid state.

“…Although several researchers are working with luminescent supramolecular network 28,29 and metal-organic frameworks (MOF) 30,31 for their potential applications in catalysis, gas storage, drug delivery and sensing; inorganic-organic frameworks are indeed scanty, particularly in fluoride sensing. The toxicant is of high concern and attracting mounting interest in the scientific community due to its duplicitous nature (used in the human diet, but, recently it has been accused of several human pathologies).…”

“…31 Here, such types of interferences have been overcome in present protonationdeprotonation strategies involved in the -NH-phenyl moiety. FSG-PAN contains a -NH proton in its molecular network, which is attackable by F -through hydrogen bonding, a recognized reaction pathway in F -sensing.…”

A time-cost effective, chemically stable mesoporous resin (FSG-PAN), simultaneous binder of two different metal centers (both high (Cd(II)) and low (Tl(I)) oxidation states), has been synthesized by immobilizing azo-dye (1-(2-pyridylazo)-2-napthol: PAN) on functionalized silica gel (FSG). Its corresponding synthesized nano material possesses good luminescent properties, and has been utilized in fluoride sensing at trace levels (1.8 × 10 -6 -7.2 × 10 -6 M). The composition.·51H2O) and structure (tetrahedral) have been well assessed. Under the optimum extraction conditions, the soft extractor (ηFSG-PAN = 1.31 eV), FSG-PAN quantitatively extracts the soft metal centers Cd(II), followed by Tl(I) at its respective HOMO and LUMO by soft-soft interactions. The extractor possesses a high Brunauer-Emmett-Teller (BET) surface area (SABET) (374 m 2 g -1 ), high preconcentration factor (PF, 192), selective pore size and two kinds of break-through capacity (BTCHOMO, 945 μmol g -1 ; BTCLUMO, 120 μmol g -1 ). BTC is spelled out as a function of the electron density over the ligand binding site as analyzed from a DFT calculation.

“…The development of selective and sensitive probe for the detection of biologically and environmentally important species has emerged as a significant goal in the field of chemical sensors (Zhou et al, 2014;Xu et al, 2010;Wang et al, 2014). So far, a number of fluorescent probes with different excitation and emission wave lengths have been used as signal receptors of chemosensors such as coumarin , pyrene (Wang et al, 2013), 1,8-naphthalimide (Dai and Xu, 2011), xanthenes , squaraine (Akkaya, 1997), cyanine (Zheng et al, 2012) and boron dipyrromethene difluoride (BODIPY) .…”

A novel, fluorescent chemosensor based on β-(2-pyridyl)acrolein-rhodamine B (RB-AC) derivative was synthesized and its sensing performance with poly(ethylene glycol) dimethacrylate (PEGDMA) polymer particle was investigated. The prepared β-(2-pyridyl)acrolein-rhodamine B/poly(ethylene glycol)dimethacrylate (PEGDMA/ RB-AC) particle was used for sensing of Al 3+. The PEGDMA/RB-AC particles showed immediate "off-on" fluorescent responses toward Al 3+. The fluorescent response was attributed to the spirolactam ring opening of RB-AC. This sensor particle showed high selectivity towards Al 3+ in the presence of other competing metal ions. The sensitivity of PEGDMA/RB-AC particle was demonstrated by confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM). The binding stoichiometry and binding mode of the metal complex was established by Job's plot and FT-IR spectroscopy.
