摘要:
A systematic investigation of the synthesis of poly(m-phenylene vinylene-co-2,5-dioctyloxy-p-phenylene vinylene) (DOP-PmPV) by Wittig-Horner condensation polymerisation reactions is presented. Large variations in yield, molecular weight distribution and optical properties in the reaction products are obtained and studies on varying reaction temperature suggest that there is an optimum temperature for this reaction, Substitution of one of the octyloxy side chains by a methoxy group yields polymer of the type MOP-PmPV. They show similar optical properties to the DOP-PmPV polymers but are found to be of lower molecular weight.
