“…In particular, sensors that can selectively detect specific molecules in various media, such as in the atmosphere or water, have been attracting attention from academics and manufacturers, and research and development of materials for that purpose have been intensifying all over the world. As some of the most promising materials that can be used in these sensors, sensing materials that use the 2-dimensional interlayer spaces of ion-exchangeable layered inorganic compounds, as introduced in reviews, have been investigated by researchers [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. For example, Yan et al reported the detection of the adsorption of aromatic compounds by a quartz crystal microbalance (QCM) device that uses an organically modified clay film [ 9 ].…”

In this study, we investigated the photoluminous spectroscopic behavior of hybrid powder incorporating both anionic fluorescein dye (AFD) and 1-butanesulfonate (C4S) with layered double hydroxide (LDH) in the presence of NH3 or NO2 gas under various relative humidity conditions. In the presence of NH3 gas, drastic photoluminescence enhancement from the LDH/AFD/C4S hybrid was observed at relative humidity (RH) ≥ 40% when the NH3 reached a certain concentration. Meanwhile, the LDH/AFD/C4S hybrid was exposed to NO2 gas at various relative humidity conditions, and the following behavior was observed: At RH ≥ 60%, the photoluminescence (PL) intensity from the hybrid gradually decreased as NO2 concentration increased. Therefore, the LDH/AFD/C4S hybrid investigated in this study is inferred to be suitable for optical NH3/NO2 sensor devices, which can be used in humid air.

“…Functional dyestuffs, such as organic boron difluoride complexes, have been useful for hitech applications such as electronics, liquid crystalline displays, sensors, electrophotography, energy storage tools, security printing, optical data storage, organic light emitting devices, light control, solar cells and photodynamic therapy [1][2][3][4][5][6][7][8][9][10][11]. Functional dyestuffs are colorants that introduce a new function upon exposure to a small quantity of external energy, such as temperature, light, and magnetic/electric field.…”

B ORON difluoride (BF 2) complex dyes are relatively non-polar and electrically neutral tending to reduce the perturbation of the conjugate functional characteristics. Consequently, they are frequently the favored choice for biological labeling. Also, their conjugates of low molecular weight structures are more likely to be permeable to live cells than other conjugates of charged chromophores. As a result of their high extinction coefficient, another significant application of boron difluoride complexes is their reactivity and high detection ability to volatile amine reagents accessible for HPLC and electrophoresis. They are more useful than the majority of other dyes with long absorption wavelength. BF 2 complex conjugates are extremely valuable reagents for many bio-analytical screening purposes, such as their affinity to quench the fluorescence upon conjugation to certain biopolymers. In this review, we discuss the preparation of boron difluoride carbonyl based-complexes, including O-O double-dentate and NO double-dentate dyes, as well as shedding light on their photophysical properties.
