There are disclosed polymeric or oligomeric product obtainable from the reaction of an anthraquinone with an aromatic diamine, characterised in that the anthraquinone is substituted or is not substituted and in that the diamine is a diamino anthracene which is substituted or is not substituted. The anthraquinone may be of the general formula (I): ##STR1## where, R may be the same as or different to R', and may be a hydrogen atom (when R=R'=H, the compound is anthraquinone), or CH.sub.3, CH.sub.3 CH.sub.2 --, --OCH.sub.3, --OCH.sub.2 CH.sub.3, --CH.sub.2 OCH.sub.3, --CH.sub.2 OCH.sub.2 CH.sub.2 OCH.sub.3, methoxyethoxyethoxymethyl, aryloxymethyl, phenyl, Cl, Br, CN or NO.sub.2, --CH.sub.2 COOR or CH.sub.2 NHCOR" (where R" is C.sub.1 -C.sub.6 alkyl or a phenyl or biphenyl group).
6835805 - Polymers - Owned by Nissan Chemical Industries Limited (Tokyo,JP)
A method of production of a homopolymer or copolymer or homo-oligomer or co-oligomer product characterised in that the product is obtained by condensation reaction of a diaminoanthracene, substituted or not, optionally with a diiminoanthracene substituted or not in the absence of anthraquinone substituted or not.
A copolymer of benzene and substituted benzene, particularly anthracene is disclosed. The copolymer is soluble in common organic solvents like chloroform, methylene chloride, benzene, toluene, dimethylformamide, N-methyl pyrrolidinone etc unlike the parent polymer poly-p-phenylene which is highly insoluble in organic solvents. The copolymer is thermally stable up to 380.degree. C. and environmentally stable for at least 1 year. The copolymer is capable of being thermally evaporated useful for electroluminescent devices. The copolymer shows electroluminescene and can be used in the fabrication of an organic light emitting diode device.
