Hyperbranched polymers with aggregation-induced emission property for solution-processed white organic light-emitting diodes

In this work, a new series of hyperbranched polymers of PFTPE-Ir(piq)3-X(X = 1, 5, 10) were designed and synthesized, in which tris(1-phenylisoquinoline)iridium(Ш) (Ir(piq)3) acts as red emission core and PFTPE acts as branches. The

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.

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.
