Abstract : Electric and magnetic properties of oligomers of type HC=C-Ar-C=CnH depend on structure of arylene part of Ar - basic link of oligomer. The introduction of the aliphatic chain between the aromatic nuclei in the arylene part interrupts conjugation, and oligomer acquires dielectric properties. In this case their solubility plays especially large role, since the possibility of obtaining of them the films is determined. Therefore for increasing the solubility and for the break of conjugation we introduced alkoxyl groups into diethynylarenes, it is analogous how hydroxide groups were previously introduced into monoethynylarenes.
