One-stage synthesis of poly[(p-phenylimino)-acenaphthene], a new macromolecular material with interesting electric properties

摘要

A new macromolecular material, a derivative of 1,2-bis-(p-aminophenylimino)-acenaphthene, was prepared.The monomer above, belonging to the group of small-molecule semiconductors, presents, as we referred in a previous work (Mhaidat [1]), remarkable photoconductive properties. The polymerization, a polycondensation reaction, was achieved in one-stage, using as starting materials acenaphthenequinone and p-phenylenediamine. in the presence of TiCl_4 and Dabco as catalysts, into o-dichlorobenzene acting as a solvent. The product obtained was fully characterized with mass spectroscopy, ~1H NMR and FTIR techniques. Mass spectrum permitted the calculation of the polymer's molecular weight, being equal to 1633.85, whereas measurements of electric properties confirmed its semiconductive character.
