A single fluorophore, single-component system for advancing white-light emission in aqueous media with ultrafast dynamical study
A polarity-sensitive single-fluorophore and -component system probe An-EA was able to generate tunable luminescence as well as white-light (0.33, 0.36) due to a broad emission spectrum containing monomer and excimer bands that are associated with nanoparticles and aggregated fiber formation, respectively in an aqueous media. In addition to the spectroscopic evidence for monomer and excimer properties in aggregated states, transient absorption spectroscopy was used to investigate charge-transfer properties between donor aniline and acceptor anthracene.
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.
