High-Performance Emission/Color Dual-Switchable Polymer-Bearing Pendant Tetraphenylethylene (TPE) and Triphenylamine (TPA) Moieties

Electrofluorochromic (EFC) materials have aroused great interest owing to their interesting ability of tuning fluorescence in response to the applied potential. However, some crucial characteristics, such as response speed, fluorescence contrast, and swit

Synergistic effect between electroactive tetraphenyl-: P -phenylenediamine and AIE-active tetraphenylethylene for highly integrated electrochromic/electrofluorochromic performances

Switchable fluorescent materials have gained great attention due to their promising applications in sensors, memory devices and displays. However, further progress is hindered by the low fluorescence contrast, modest response speed and inferior long-term cycling stability. Based on a rational design strategy by combining a highly conjugated tetraphenyl-p-phenylenediamine (TPPA) unit and an aggregation induced emission (AIE)-active tetraphenylethylene (TPE) unit, we synthesized a novel diamine "N,N′-bis(4-aminophenyl)-N,N′-di(4-(1,2,2-triphenylethenyl)phenyl)-1,4-phenylenediamine" to construct an electro- and AIE-active polymer. In addition to the high efficiency solid-state fluorescence and the extremely stable redox properties, the resulting polymer TPE-TPPA-PA realized highly integrated emission/color dual-switchable properties, including multistage color-changing, high fluorescence on/off contrast up to 252, impressively rapid response rate (1.3/0.5 s for EC and 0.7/2.1 s for EFC processes) and excellent cycling stability over 10000 s. The demonstrated synergistic effect between stable electroactive TPPA and AIE-active TPE may provide a new pathway for further molecular design to realize high-performance emission/color dual-switchable materials.

Enantiomeric selectivity of ruthenium (II) chiral complexes with antitumor activity, in vitro and in vivo

Different enantiomers of chiral drugs show distinctive activities. Here, a pair of chiral ruthenium Λ-[Ru(phen)2(TPEPIP)]2+ (Λ-Ru), and Δ-[Ru(phen)2(TPEPIP)]2+ (Δ-Ru) (phen = 1,10-phenanthroline; TPEPIP = 2-(4′-(1,2,2-triphenylvinyl)-[1,1′-biphenyl]-4-yl)-1H-imidazo[4,5-f][1,10]phenanthroline) compounds have been prepared and characterized. Both have aggregation-induced emission characteristics, although Λ-Ru exhibits much higher activity, towards duplex DNA extracted from SGC-7901 cancer cells. In vitro experiments demonstrate that both Λ-Ru and Δ-Ru can induce the apoptosis of tumor cells with Λ-Ru showing greater activity than Δ-Ru. Λ-Ru aggregates in the cell nucleus of SGC-7901 within 5 h which shows that nucleic acids may be the effective target of Λ-Ru. In vivo experiments with nude mice showed that Λ-Ru can inhibit the growth and proliferation of a tumor, in tumor-bearing mice as well as targeting the tumor site, as demonstrated by fluorescence. These results demonstrate the dual-function of Λ-Ru, which could be used for real-time visualization of a chemotherapeutic agent.

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.
