“…It shows that the structure changes before and after the phase transition (383 K/380 K), which makes the fluorescence intensity significantly reduced, but there is no red shift or blue shift, which is similar to the results of previous studies. [31][32][33][36][37][38][39] This result well proves that 1 and 2 have good fluorescence characteristics and are good potential luminescent materials, which will expand their application fields.…”

Bistable switches (electrical switching between "ON" and "OFF" bistable states) have gradually developed into an ideal category of highly intelligent materials, due to their significant applications in optical technology, signal processors, data storage and other switchable media applications in the field of electrical devices. Here, we successfully designed and synthesized4fluoro-phenethylamine; M = Cd (1), Mn (2)), which realized the coupling of thermo-dielectric switching characteristics, semi-conductor characteristics and photo-luminescent properties. DSC (differential scanning calorimetry) and dielectric measurements show that 1 is a sensitive dielectric bistable switch between the high dielectric (ON) and low dielectric (OFF) states. The temperature-variable single crystal structure shows that the both 1 and 2 undergo a high-temperature reversible phase transition around 383 K/380 K, which is caused by the order-disordered transformation of organic cations and the slight distortion of the inorganic framework. In particular, 1 shows outstanding switchable dielectric behavior and semiconducting properties. Further, 1 and 2 emit strong green and yellow luminescence at 527 and 595 nm, respectively.

“…In this regard, considerable effort has been devoted to developing methods of analysis for toxic heavy metals in both industrial processes and environmental systems. However, the traditional analysis methods for detecting traces of Cd 2+ are expensive, such as atomic absorption spectrometry (AAS), inductively coupled plasma mass spectrometry (ICP-MS), and fluorometric and colorimetric sensors . Many fluorescent probes for cadmium have been developed in the past decade.…”

We prepared the monomer PCDA-HP composed of 5-hydroxy-N 1 ,N 3 -bis(pyridin-2-ylmethyl)isophthalamide (HP) as a cadmium ion tweezer and then polymerized them to form a polydiacetylene (PDA)-based sensor (PDA-HP), which displayed selective and sensitive colorimetric and fluorometric change upon addition of a cadmium ion (Cd 2+ ) at both pH 7.4 and 6.8. The PDA-HP polymer was highly selective for Cd 2+ over other metal ions with colorimetric change. In addition, the PDA-HP chemosensor also showed a red fluorescence change in the presence of Cd 2+ at both pH 7.4 and 6.8. Naked-eye detection of Cd 2+ was accomplished in an aqueous solution through a PDAbased sensor system. Finally, the lowest energy structure of an HP chelator was obtained by the crystal structure and density functional theory (DFT) calculations.

An aptasensor for the detection of ochratoxin A (OTA) in environmental samples was developed. It displayed high sensitivity and good selectivity. Factors such as specific binding between a FAM (5-carboxyfluorescein)-labeled aptamer (f-RP) and OTA, and a magnetic property of a streptavidin magbeads-modified capture probe (bm-CP) resulted in aptasensor’s linear relationship between fluorescence intensity and the concentration of OTA. This characteristic is present at the OTA concentration ranges from 0.100 μM to 25.00 μM with a LOD (limit of detection) of 0.0690 μM. The bm-CP can be reused through melting, washing and magnetic separation, which contributes to cost reduction. In addition, the proposed method is simple and detection process is fast. The aptasensor can be used in real samples.
