  • Publication number: 20090032811
    Abstract: A method is provided for modifying a poly(arylene vinylene) or poly(heteroarylene vinylene) precursor polymer having dithiocarbamate moieties by reacting it with an acid and further optionally reacting the acid-modified polymer with a nucleophillic agent. Also provided are novel polymers and copolymers bearing nucleophillic side groups which are useful as components of electronic devices, e.g. in the form of thin layers.

  • Patent number: 7446164
    Abstract: A technique is described for the preparation of polymers according to a process in which the starting compound of formula (I) is polymerized in the presence of a base in an organic solvent. No end chain controlling agents are required during the polymerisation to obtain soluble precursor polymers. 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 towards a soluble or insoluble conjugated polymer by thermal treatment. The arylene or heteroarylene polymer comprises structural units of the formula III. In this 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 5000 to 1000000 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).

  • Publication number: 20080045684
    Abstract: 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).

  • Publication number: 20060079648
    Abstract: The present invention provides a conjugated polymer with provided thereon at least one molecular imprinted polymer (MIP) and a method for preparing such a polymer. The conjugate polymer provided with at least one MIP according to the invention combines both transducer properties and selectivity properties in one single material. Therefore, it is particularly suitable for use in chemo- or bio-sensors. Furthermore, the conjugate polymer provided with at least one MIP may be used in electronic devices and in chromatography, molecular recognition, selective sample enrichment or in catalysis.
