Abstract The synthesis and structure of the p ‐hydroxybenzoic acid polymer is described. was successfully prepared from either phenyl ester or ‐acetoxybenzoic acid. With highly purified acetoxybenzoic acid, single crystals could be prepared. determined shown to consist a double helix where two chains are in reversed head‐to‐tail order. unit cell dimensions are: = 17.8 Å c 18.4 Å, corresponds chain length with repeat distance three units. mechanism polymerization formation crystal discussed....

A novel, simple but efficient diamine (TriPEDA) containing rigid nonplanar conjugated triphenylethylene moieties was designed and synthesized through Wittig–Horner Suzuki coupling reactions. Four kinds of high-performance functional polyimides were thus prepared by the dipolymerization TriPEDA four dianhydrides, respectively. Because introduction aromatic structure, exhibited special fluorescent resistive switching (ON-OFF) characteristics, as maximum fluorescence emission observed at...
Activated carbon fibers (ACFs) were oxidized using both aqueous and nonaqueous treatments. As much as 29 wt % oxygen can be incorporated onto the pore surface in form of phenolic hydroxyl, quinone, carboxylic acid groups. The effect oxidation on size, volume, chemistry was thoroughly examined. average micropore size is typically affected very little by while volume area decreases with such a treatment. In contrast, increase air. Oxidation produces chemistries that provide for enhanced...

The crystallographic structure of organic crystals is most commonly studied using x-ray diffraction (XRD) techniques. Unfortunately, rather large crystals, at least 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sup> µm xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> , are required for XRD analysis, and it often quite difficult sometimes impossible to prepare such crystals. On the other hand, electron techniques, although not nearly as...
