Abstract
Two pyridinium amide-based receptors L1 and L2 with a small difference of H-bond position
of the amide have been synthesized and characterized. Interestingly, they exhibited a huge difference in
sensing towards AcO- and H2PO4
-, respectively. Receptor L1 was found to be ‘naked-eye’ selective for
AcO- anions, while receptor L2 showed clear fluorescence enhancement selective to H2PO4
- anion. The
recognition ability has been established by fluorescence emission, UV-vis spectra, and 1HNMR titration.

Abstract
In this study, the recognition contour of Chemosensor 1 was investigated using semiaqueous methanol (XH , mole fraction = 0.31) for a range of anions and bioactive species. Host-receptor signalling based on the internal charge transfer mechanism for Chemosensor 1 was explored and reported. Structure of Chemosensor 1 and its plausible anion coordination based on hydrogen bonding is complemented with density functional theory. Consequently, we investigated the applicability of the synthesized probe in blood plasma, urine, tap water samples, and for monitoring of ATP in lysosomes by apyrase enzyme.

Abstract
In this manuscript, a new colorimetric and fluorescent chemosensor (T) was designed and synthesized, it could successively detect Cu2+ and H2PO4- in DMSO/H2O (v/v=9:1, pH=7.2) buffer solution with high selectivity and sensitivity. When added Cu2+ ions into the solution of T, it showed a color changes from yellow to colorless, meanwhile, the green fluorescence of sensor T quenched. This recognition behavior was not affected in the presence of other cations, including Hg2+, Ag+, Ca2+, Co2+, Ni2+, Cd2+, Pb2+, Zn2+, Cr3+, and Mg2+ ions. More interestingly, the Cu2+ ions contain sensor T solution could recover the color and fluorescence upon the addition of H2PO4- anions in the same medium. And other surveyed anions (including F-, Cl-, Br-, I-, AcO-, HSO4-, ClO4-, CN- and SCN-) had nearly no influence on the recognition behavior. The detection limits of T to Cu2+ and T-Cu2+ to H2PO4- were evaluated to be 1.609×10-8M and 0.994×10-7M, respectively. In addition, the sensor T also could be served as a recyclable component and the logic gate output was also defined in sensing materials. The test strips based on sensor T were fabricated, which acted as a convenient and efficient Cu2+ and H2PO4- test kits.

Abstract
A novel ion-imprinted electrochemical sensor based on AlGaN/GaN high electron mobility transistors (HEMTs) was developed to detect trace amounts of phosphate anion. This sensor combined the advantages of the ion sensitivity of AlGaN/GaN HEMTs and specific recognition of ion imprinted polymers. The current response showed that the fabricated sensor is highly sensitive and selective to phosphate anions. The current change exhibited approximate linear dependence for phosphate concentration from 0.02 mg L−1 to 2 mg L−1, the sensitivity and detection limit of the sensor is 3.191 μA/mg L−1 and 1.97 μg L−1, respectively. The results indicated that this AlGaN/GaN HEMT-based electrochemical sensor has the potential applications on phosphate anion detection.

Abstract
Hydrogels of low molecular weight molecules are important in biomedical applications. Multiple factors are responsible for hydrogel formation, but their role in governing self-assembly to hydrogel formation is poorly understood. Herein, we report the hydrogel formation of fluorenylmethyloxycarbonyl phenylalanine (FmocF) molecule. We used physical and thermal stimuli for solubilizing FmocF above the critical concentration to induce gel formation. The key role of Fmoc, Fmoc and phenylalanine covalent linkage, flexibility of phe side chain, pH, and buffer ions in self-assembly of FmocF to gel formation is described. We found that the collective action of different non-covalent interactions play a role in making FmocF hydrogel. Using powder diffraction and infrared spectroscopy, we also report a new polymorphic form of FmocF after transitioning to hydrogel. In addition, we are proposing a model for drug release from FmocF hydrogel.
