A Reaction-Based Colorimetric Fluoride Probe: Rapid “Naked-Eye” Detection and Large Absorption Shift
关键字：azobenzenes, charge transfer, colorimetric
Taking advantage of both the well-known azobenzene structure and the special fluoride-promoted cleavage reaction of the SiO bond, a new ratiometric colorimetric probe (F-1) toward the fluoride anion was designed and synthesized by using intramolecular charge transfer (ICT) as a signal mechanism. Upon the addition of F ions, the probe displayed apparent color changes from colorless to deep blue...

Dynamic Self-Assembly Induced Rapid Dissolution of Cellulose at Low Temperatures
关键字：cellulose, low temperature, urea
Cellulose can be dissolved in precooled (-12 °C) 7 wt % NaOH-12 wt % urea aqueous solution with in 2 min. This interesting process, to our knowledge, represents the most rapid dissolution of native cellulose.The results from 13C NMR, 15N NMR, 1H NMR, FT-IR, small-angle neutron scattering (SANS), transmission electron microscopy (TEM), and wide-angle X-ray diffraction (WAXD) suggested ...
