Handy ratiometric detection of gaseous nerve agents with AIE-fluorophore-based solid test strips

Exposure to odorless, colorless, tasteless and yet lethal nerve gases could lead to paralysis of the central nervous system, organ failure or even rapid death. Hence it is of great importance to develop a convenient, portable and rapid detection method for these gaseous nerve agents. Herein, based on the aggregation-induced emission (AIE) characteristics, a ratiometric fluorescent test-strip sensor (DPA-TPE-Py) for rapid, sensitive and selective detection of the gaseous nerve agent simulant diethyl chlorophosphate (DCP) has been developed. It is easy to prepare handy and portable solid test strips via direct deposition of AIE probes onto the filter paper. Moreover, when the test strips are exposed to DCP vapor, their fluorescence changes from yellow to orange red. The detection limit for DCP is as low as 1.82 ppb, lower than the reported Immediately Dangerous to Life or Health concentration (IDLH concentration). Such a strategy could provide helpful insights into designing convenient cost-effective ratiometric fluorescent sensors in the solid state as well as affording a portative method for detection of gaseous nerve agents.

“Colorless-to-black” electrochromic and AIE-active polyamides: An effective strategy for the highest-contrast electrofluorochromism

Electrofluorochromic (EFC) materials have gained extensive attention owing to their interesting modulations of fluorescence by an electric stimulus. However, the limited performances, especially the low fluorescence on/off contrast, significantly hampered

Aggregation-induced emission-active hyperbranched polymers conjugated with tetraphenylethylene for nitroaromatic explosive detection

This work develops a facile synthesis for aggregation-induced emission (AIE)-active hyperbranched polyglycidols (HPGs) to design a solid-state sensor for detecting nitroaromatic explosives. The tetraphenylethylene moieties were conjugated onto the periphery of the HPGs in a single step using dynamic boronate ester cross-linkers. The resulting AIE-active HPGs exhibited excellent AIE characteristics in tetrahydrofuran (THF)/H2O mixtures, emitting a strong blue fluorescence under UV irradiation. Dynamic light scattering and transmission electron microscopic analyses demonstrated that the self-assembled nanosized aggregates were stable in the THF/H2O mixture. The fluorescence of the aggregates was dramatically quenched by various nitro compounds, including 2,4,6-trinitrophenol (or picric acid; PA), 2,6-dinitrophenol, 4-nitrophenol, 4-nitrotoluene, and nitromethane. The nano-aggregates exhibited extraordinary sensitivity towards PA, with a Stern?Volmer constant (Ksv) of 2.27 × 104 M?1 and a limit of detection of 40 ppb. Paper strips encapsulating the aggregates exhibited a vivid visual quenching, promising the practical applicability of these polymers as solid-state sensors for the detection of nitroaromatic explosives.

Facile preparation of a tetraphenylethylene-doped metal-organic framework for white light-emitting diodes

A highly emissive fluorophore, 1,2-bis(4-(4-carboxyphenyl))-1,2-diphenylethene (H2BCPPE), has been successfully introduced into a bio-MOF-101-archetype structure via solvent-assisted ligand exchange (SALE). The crystallinity and topological structure of the as-synthesized compound are retained after ligand exchange. The exchange ratio of the BCPPE ligand in bio-MOF-101-BCPPE reaches 18.3 mol% as determined by 1H NMR spectra of the dissolved samples. Additionally, bio-MOF-101-BCPPE exhibits broadband white emission with CIE coordinates of (0.35,0.36), under an excitation wavelength of 375 nm and an applied bias of 3 V; therefore, it can be used as a white light-emitting diode (WLED). This work can be easily extended to other porous materials for the design and preparation of new light devices.

Synthesis of new aryl and hetaryl dibromides and diiodides, the monomers for preparation of polyarylene ethynylenes

Dibromides and diiodides with quinoxaline, phenylimidazole, and hexa-or pentaphenylarylene fragments were synthesized from dihalotolans obtained from chloral. Oligoarylene ethynylenes were synthesized by the reaction of the monomers with equimolar amounts of diethynyl aromatic compounds in the presence of the Pd11 complex. Oligomers with imidazole and hexa(penta)arylbenzene cycles are soluble in amide organic solvents and their reduced viscosities do not exceed 0.09 dL g-1.

Halogen Bonding Tetraphenylethene Anion Receptors: Anion-Induced Emissive Aggregates and Photoswitchable Recognition

A series of tetraphenylethene (TPE) derivatives functionalized with highly potent electron-deficient perfluoroaryl iodo-triazole halogen bond (XB) donors for anion recognition are reported. 1H NMR titration experiments, fluorescence spectroscopy, dynamic light scattering measurements, TEM imaging and X-ray crystal structure analysis reveal that the tetra-substituted halogen bonding receptor forms luminescent nanoscale aggregates, the formation of which is driven by XB-mediated anion coordination. This anion-coordination-induced aggregation effect serves as a powerful sensory mechanism, capable of luminescence chloride sensing at parts per billion concentration. Furthermore, the doubly substituted geometric isomers act as unprecedented photoswitchable XB donor anion receptors, where the composition of the photostationary state can be modulated by the presence of a coordinating halide anion.
