• Identification and quantification of <i>cis</i> and <i>trans</i> isomers in aminophenyl double-decker silsesquioxanes using ¹ H-²⁹ Si gHMBC NMR
  作者：B.W. Schoen、D. Holmes、A. Lee

  DOI：10.1002/mrc.3962

  日期：2013.8

  Cis and trans isomers of a series of double-decker silsesquioxanes (DDSQ) were characterized by two-dimensional NMR techniques. The (1)H NMR spectra of these species have not previously been assigned to a degree that allows for quantification. Thus, (1)H-(29) Si HMBC correlations were applied to facilitate (1)H spectral assignment and also to confirm previous (29)Si assignments for this class of silsesquioxanes

  通过二维NMR技术对一系列双层倍半硅氧烷（DDSQ）的顺式和反式异构体进行了表征。这些物质的（1）H NMR谱图以前尚未分配给可以量化的程度。因此，应用（1）H-（29）Si HMBC相关性可促进（1）H光谱分配，并确认此类倍半硅氧烷的先前（29）Si分配。具有识别（1）H NMR光谱的所有相关共振的能力，（29）Si NMR不再需要进行定量分析，而仅需要进行表征。这不仅节省时间和材料，而且提供了更准确的定量，因此可以确定每种化合物中存在的顺式和反式异构体的比例。
• Thermal Transitions and Reaction Kinetics of Polyhederal Silsesquioxane containing Phenylethynylphthalimides

  日期：2010.11.23

  Thermal transitions and reaction kinetics of polyhedral oligomeric silsesquioxane (POSS) with phenylethynylphthalimide (PEPI) moieties were investigated Specifically, this study was designed to probe the influence of the POSS peripheries, types of spacer group in between the PEPI and the SiO1 5 core, the architecture of the PEPI arrangement with respect to the SiO1 5 core, and the number of PEPI groups per cage on the thermal transitions and the cross linking reaction of phenylethynyl PEPI-POSS compounds with isobutyl peripheries exhibited lower melting temperatures as compared to those with phenyl periphery consequently these isobutyl PEPI-POSS derivatives have a higher phenylethynyl reaction rate, although the onset of reaction temperature was not significantly affected Changing the spacer group from propyl to phenyl causes an increase in the melting transition temperature along with a higher heat of fusion at melting however, the more rigid phenyl spacer enables the PEPI-POSS to form a higher degree of crystallinity upon cooling The more rigid phenyl spacer also initiates the polyene reactions at lower temperatures For POSS with PEPI attached to either side of the cage, there are two isomers with respect to the SiO1 5 core This mixture of two isomers inhibits the formation of crystallinity as compared with the 'pendent' derivative where both PEPI groups come off from the same corner of FOSS cage Finally, it was found that these PEPI-POSS molecules have reaction kinetics and onset temperatures on par with organic hexafluorophenylethynyl oligoimides, which make these PEPI-POSS molecules excellent candidates as nanocomposite additives in high performance composite applications

  Novel POSS mono- and dianiline compounds, their synthesis procedures, and applications in host materials for the purposes of property enhancement are described. This class of POSS compounds features completely aromatic peripheries and partial amine functionality for facile and controlled reactive incorporation into a variety of polymers, and further utility may be derived from reactions of the available amine groups with anhydrides such as phenylethynyl phthalic anhydride (PEPA) to form reactive imide-type oligomers for incorporation into high performance thermosetting polymers. Modification of polymer hosts with the subject nanoparticles can result in a variety of property improvements including mechanical, thermal, tribological, electrical, as well as improved moisture resistance.
