  Solid-State NMR Characterization of 13 C- and 15 N-Labeled Phthalimides as Model Compounds for Studying Polyimides

  摘要：

  N-15 CSA spectra were acquired for four isotopically labeled bisphthalimide compounds. The N-15 CSA tenser elements (delta(11), delta(22), and delta(33)) for the labeled derivatives were determined from CSA lineshape analysis. In addition, the CSA spectrum for the N-15, C-13-labeled N-methylphthalimide was obtained. From CSA lineshape analysis, it was determined that delta(33) lies approximately along the N-C bond axis, with delta(22) assumed to be approximately perpendicular to the imide plane. The angles alpha and beta were found to be 90 degrees and 7 degrees, respectively. The dipolar coupling constant for the C-13-N-15 bond was 883 Hz, corresponding to a bond length of 1.51 Angstrom.

  The synthesis of [15N]-1,1,3,3-tetrakis(trideuteriomethyl)isoindolin-2-yloxyl and of some 5-alkyl derivatives have been achieved by standard synthetic routes.1 The presence of deuterium improves the sharpness of the signals, and this, together with the incorporation of nitrogen-15, enhances the application of such compounds as spin probes; alkyl substituents at C-5 improve the lipophilicity.

  [15N]-1,1,3,3-四（三氘代甲基）异吲哚啉-2-基氧基和一些 5-烷基衍生物的合成已通过标准合成路线实现。1 氘的存在提高了信号的清晰度，这与氮 15 的掺入一起增强了此类化合物作为自旋探针的应用； C-5处的烷基取代基提高了亲脂性。
