Construction of white light “On-Off-On” supramolecular materials for relay detection of Fe3+ and H2PO4−
White light materials are of great interest due to their wide potential applications in lighting devices, displays and probes. Herein, a novel bis-component white light-emitting supramolecular polymer gel TBG was facilely constructed from tripodal pyridine amides and tripodal imidazole by host–guest self-assembly process. Interestingly, the TBG exhibits strong aggregation-induced emission and can be used for highly efficient and sensitive fluorescence detection of ions (Fe3+ and H2PO4−) via the fluorescence “On-Off-On” pathway. The limits of lowest detection limits (LODs) for Fe3+ and H2PO4− were calculated to be 10.08 nM and 21.87 nM, respectively. Meanwhile, the xerogel of TBG could adsorb and separate Fe3+ from aqueous solutions, and the adsorption rate reached 99 %. In addition, a thin film based on the TBG could be used as a convenient test kit for the fluorescence detection of Fe3+ and H2PO4−.
期刊介绍：
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
