PURPOSE:To establish a synthetic technique, and to improve reproducibility by composing the title magnet of a three-dimensional ladder polymer using the tetraimido derivative of octacarboxylic acid having the heterocycle of a phenylhydrazine type skeleton shown in specific structural formula as a repeating unit. CONSTITUTION:A synthetic organic high-molecular magnet consists of the magnetic organic high-molecular material of three-dimensional ladder type polyimide structure having the heterocycle of a phenylhydrazine type skeleton in a main chain, and is made up of a three-dimensional ladder polymer employing the tetraimido derivative of octacarboxylic acid having the heterocycle of the phenylhydrazine type skeleton in formula as a repeating unit. The magnetic organic high-molecular material is formed by reacting a substance having a bissydnone group and a substance having a bismaleimide group and generating a 1, 3-dipole multi-pie additional cyclic reaction. The magnet is dissolved into an organic solvent and can be changed into a magnetic fluid, and can be utilized for novel various application. |
