Definitions
- the invention relates to new thiophenes which are suitable for the production of electrically conductive polymers and a process for their polymerization.
- the polythiophenes are usually prepared by chemical or electrochemical polymerization of monomeric or oligomeric thiophenes.
- the invention relates to novel thiophenes of the formula I which are suitable for the production of electrically conductive polymers
- the resulting polythiophenes can often not be processed.
- a further part of the invention therefore relates to a new polymerization process in which polythiophenes which can be processed in solution and which, after protonation with an acid, have a high and stable electrical conductivity without the problems mentioned above.
- the invention therefore also relates to a process for the preparation of polythiophene, characterized in that thiophenes of the formula I
- Suitable acids are formic acid, difluoroacetic acid, trifluoroacetic acid and dichloroacetic acid.
- the process according to the invention is preferably carried out with formic acid.
- the process is preferably carried out at a reaction temperature of 10 to 60 ° C. Since the resulting polymers are compounds not known to date, the invention further relates to the polythiophenes of the formula II
- the polythiophenes of the formula II are in cationic form due to protonation of the benzo-bis [1,2,5] thiadiazole units.
- the positive charges are not shown in the formula because the charges are delocalized over the entire molecule.
- the polythiophenes of the formula II can be reversibly switched between a positively charged and neutral state by adding or removing an acid which has a pK g value of ⁇ 3.75 and whose corresponding conjugate base is non-nucleophilic.
- Particularly important areas of application of the polythiophenes of the formula II are, for example:
- Electrodes light emitting diodes, field effect transistors,
- the conductivity of the polythiophenes of the formula II in the protonated state is between 10 8 and 10 3 S / cm, preferably between 10 -4 and 10 2 S / cm.
- the polythiophenes of formula II have been characterized using various techniques, e.g. UV-Vis-NIR spectroscopy, FT-IR spectroscopy, viscosity analysis, GPC, conductivity analysis, MALDI-TOF MS, NMR spectroscopy, cyclic voltammetry and microanalysis (C, H, N, etc.).
- various techniques e.g. UV-Vis-NIR spectroscopy, FT-IR spectroscopy, viscosity analysis, GPC, conductivity analysis, MALDI-TOF MS, NMR spectroscopy, cyclic voltammetry and microanalysis (C, H, N, etc.).
- the thiophenes are obtained by reacting benzobis [1,2,5] thiadiazole dione, which is readily available from tetraaminobenzoquinone and SOCl 2 , with the corresponding 2-thienyllithium derivative, which is readily available from the corresponding thiophene derivative and n-butyllithium, or the second -Thienylbromomagnesium derivative manufactured.
- the polymerization is carried out with formic acid. example 1
- Fine powdery 4,8-dihydroxy-4,8-bis (2-thienyl) benzo [1,2-c: 4,5-c '] - bis [1,2,5] thiadiazole (25 mg) was added
- Formic acid (10 ml) added and 12 hours at room temperature stirred.
- the resulting solution of the polymer in formic acid can then be used directly, for example, in the compressed air rotation process.
