抄録

In order to achieve photo-responsive super-high spin organic compounds, preparations and magnetic properties after irradiation of dendritic polymers having diazo groups connected by diphenylacetylenes were investigated in this work.Polyketone precursor of the polydiazo polymer was prepared by Sonogashira reaction of core triiodo compound and branched diiodoethynyl compound followed by reaction with terminating tetraalkyloxy compound.Components having molecular weight larger than about 3 x 10<sup>3</sup> was separated by GPC and was used in following experiments.The polyketone polymer was converted to polydiazo polymer by the usual method through hydrazone compound.Magnetic properties after photolysis of the polydiazo polymers in 2-MTHF frozen solutions were investigated by SQUID. The curve fitting for the field dependence of magnetization at 5 K provided the average spin multiplicities of the photoproducts as S = 6.3.
