Method of preparing derivatives of polyarylene vinylene and method of preparing an electronic device including same

摘要

A technique is described for the preparation of polymers according to a new process, in which the starting compound of formula (I) is polymerized in the presence of a base, in an organic solvent. The precursor polymer such obtained comprises structural units of the formula (II). In a next step, the precursor polymer (II) is subjected to a conversion reaction by thermal treatment. The arylene or heteroarylene polymer comprises structural units of the formula III. In this new process the dithiocarbamate group acts as a leaving group and permits the formation of a precursor polymer of structural formula (II), which has an average molecular weight from 5.000 to 500.000 Dalton and is soluble in common organic solvents. The precursor polymer with structural units of formula (II) is thermally converted to the conjugated polymer with structural formula (III).
