Highly efficient solid-state emission of diphenylfumaronitriles with full-color AIE, and application in explosive sensing, data storage and WLEDs

Luminescent materials with aggregation-induced emission (AIE) have attracted extensive attentions for their strong emission in aggregated states. Although all kinds of AIE luminogens have been recently developed, it is difficult to realize full-color AIE which is popular for the various applications in optoelectronic fields. Herein, a class of diphenylfumaronitrile core-based dyes emitting in a wide region from near ultraviolet (382 nm) to near-infrared (682 nm) have been synthesized and well characterized. It is found that the emission wavelength of the dyes severely depends on the peripheral substituent, including electron-withdrawing trifluoromethyl (1), methyl (2), electron-pushing methoxyl (3), and bulky aromatic amine (7–9), and that the substituting location imposes great effect on the emission intensity of multiple-substituted dyes (4–6). Compound 4 with two methyl substituting at 3,4-position gives a ultrahigh quantum yield of 93percent for unique packing structure. 1–3 and 7 can be used in explosive detecting and data storage for their emission sensitive to picric acid and external stimuli, respectively. When 4 and 8 applied in white-light-emitting diodes (WLEDs), a pure white emission can be obtained with 90 of CRI and (0.32, 0.32) of CIE.

The presently described water-soluble conjugated polyene compound are useful as bioprobes for the detection of biomacromolecules, in the manufacture of sensors, in monitoring and retarding formation of amyloid protein fibril in vitro and in vivo, and in developing anti-cancer drugs.

Generation and reaction of ammonium ylides in basic two-phase systems

Reaction of the quaternary ammonium salts 2a-i with electrophilic alkenes 3, active alkylating agents 7 or aromatic aldehydes 11, carried out in basic two-phase systems A-D, afforded cyclopropanes 4, cyanoalkenes 8 or cyanooxiranes 12 respectively, via the corresponding ammonium ylides 2+-. The method is very simple, and gives cyclopropanes 4 and cyanoalkenes 8 in high yield. Under similar conditions, 1-cyanodienes 8aa,ba were cyclopropanated at the γ,δ-double bond with formation of vinylcyclopropanes 9a,b. The stereochemistry of the prepared cyclopropanes was elucidated from literature, 1H NMR spectroscopic data, NOE experiments or X-ray single crystal analysis. Wiley-VCH Verlag GmbH & Co.
