“…Due to the interaction between As 3+ and bipyridyl hindering the PET process of the COF to cause fluorescence quenching, the fluorescent COF could be applied as a fluorescent probe for rapid and sensitive detection of As 3+ with the detection limit of 8.86 nm. 107 Trabolsi and coworkers prepared a porphyrin-based PV-COF by the modification of viologen, for effectively removing bromate (BrO 3À ) from water through hydrogen interaction and electrostatic interactions, possessing a maximum adsorption capacity of 203.8 mg g À1 . Furthermore, the effect of reduced viologen unit to cationic form and metal zinc modified COF on bromate adsorption was investigated, and it was found that the driving force of adsorption was derived from ion exchange and hydrogen bond formation (Fig.…”

“…In particular, 2D COFs may be the best candidate for the detection of highly toxic ions such as As 3+ . Yin and Liu reported functional COFs based on bipyridine (Dpy-TFPB) for the fluorescence “turn on” mode detection of As 3+ [ 72 ]. The synthesis method and structure of Dpy-TFPB are shown in Figure 6 .…”

Arsenic is a toxic non-metallic element that is widely found in nature. In addition, arsenic and arsenic compounds are included in the list of Group I carcinogens and toxic water pollutants. Therefore, rapid and efficient methods for detecting arsenic are necessary. In the past decade, a variety of small molecule fluorescent probes have been developed, which has been widely recognized for their rapidness, efficiency, convenience and sensitivity. With the development of new nanomaterials (AuNPs, CDs and QDs), organic molecules and biomolecules, the conventional detection of arsenic species based on fluorescence spectroscopy is gradually transforming from the laboratory to the portable kit. Therefore, in view of the current research status, this review introduces the research progress of both traditional and newly developed fluorescence spectrometry based on novel materials for arsenic detection, and discusses the potential of this technology in the rapid screening and field testing of water samples contaminated with arsenic. The review also discusses the problems that still exist in this field, as well as the expectations.

Among the many fluoropolymers, polyvinylidiene fluoride (PVDF) has been well-known since 1960s and is preferred for various electronic applications owing to its lower cost, inordinate mechanical properties, and tunable polymorphism. It is well known that PVDF exhibits five different crystalline polymorphs (α). Among all, β-crystalline phase is the most important with excellent piezoelectric, ferroelectric, and pyroelectric properties.Metal oxide nanoparticles (MO-NPs) are used in diverse applications, aided by their unique electrical, optical, magnetic, and catalytic properties. Many reports are available with a focus on the synthesis of Fe, Co, and Ni oxide magnetic NPs for data storage and sensor applications. More importantly, transition metal cations can exist in several different valence states and their crystallite size increased with increasing addition of metal doping. Incorporation of MO and doped MO with PVDF plays pivotal a role in improving the sensitivity of the piezoelectric sensor. This review covers the doping of PVDF with MO-NPs and their effectiveness towards in applications.
