Phthalonitriles substituted with aryloxy and alkoxy groups have been synthesized and characterized by elemental analyses, IR, mass spectra and 1H NMR spectroscopy. And four of such crystal structures have also been determined. In the crystal structures, the major inter- molecular interactions between the neighboring molecules are the hydrogen bonds as C≡N···H and C-O···H that lead to similar networks in the crystal structures. 相似文献

The parallel ion energy distribution of a synthesized plasma can be readily controlled via plasma potential gradients in the
ion source chamber(s). Alternatively, layers of electrically biased metal filaments can introduce an isotropic ion heating. 相似文献
