• Support of single, double and triple bonds
The reason might lie on the fruitful p-electrons of N, O and triple bond
, which can form covalent bonds between the molecules and the ion surface, capture H to release the acidity and even join the isatin Schiff base molecules as "bridges" to conform the protective film on the ion surface.
The carbon-carbon triple bond
FTIR band was greatly diminished following a 15 minute hold at 37500, indicating reaction was near completion and/or the remaining concentration of triple bonds
was below the instrument's detection limit.
Each filament appears as 300 to 500 carbon atoms, lined up in a row and linked together by alternating single and triple bonds
, Lagow says.
"3D Molecules Edit & Test" is a very effective app for this purpose as it allows organic and inorganic molecular structures to be built with single, double and triple bonds
, as well as cyclic compounds.
The results of Fourier transform infrared (FTIR), UV-Visible absorption spectra, X-ray photoelectron spectroscopy (XPS) and on-line MS revealed that extensive conjugation has been formed in the PPBN thin films and the polymerization of benzonitrile took place mainly through the opening of carbon-nitrogen triple bonds
. The morphology characterized by field emission microscopy (FEM) indicated that the fine, homogenous and brown transparent films could be obtained at comparatively low discharge power.
