,Polyazomethines. Synthesis, properties and applications (review)

Polyazomethine and polyphenylene based on 1,2-bis(4-acetylbenzyl)-o-carborane

“…. 1 Synthesis of model compound 3. 1,2-Bis(4-acetylbenzyl)-оcarborane (1) (0.35 g, 0.85 mmol), aniline (0.165 mL), toluene (5 mL), and calcined molecular sieves 5 Å were placed into a Schlenk test-tube equipped with a refl ux condenser and a calcium chloride tube.…”

“…Toluene was distilled over sodium in an argon atmosphere, degassed using two freeze-thaw cycles, and stored over sodium. 1 H NMR spectra were recorded on an AVANCE 400 spectrometer at room temperature (solvent CDCl 3 ), IR spectra were recorded on a Bruker Vertex-70 FTIR spectrometer (in KBr pellets) in the range 400-4000 cm -1 .…”

“…Polyazomethines (poly(Schiff base)s) are a promising class of heat-resistant high-molecular-weight compounds. 1 The presence of an electron pair on the nitrogen atom allows the modifi cation of optical properties of polyazomethines. In addition, the imino group in polyazomethines is capable of protonation, complexation, and doping with electron-defi cient compounds.…”
