New conjugated oligomers were synthesized by reacting diphenylacetylene under high pressure of 0.13-0.76 GPa at 250 and 300ะŠC for 1-10 h. The numberaverage molecular weight M V n , and the weight-average molecular weight M V w increased with pressure, but those values were independent of temperature

Reducing sugars and sodium hydroxide react with phthalonitrile and 4-methoxyphthalonitrile to form mixtures of the phthalocyanine and oligomers. The oligomers, obtained in yields up to 54%, were deduced to have a structure that is predominantly polyazine with the o-cyanophenyl group as a substituent
