摘要:
The invention relates to novel polymers containing repeating units based on benzo[1,2-d;4,3-d′]bisthiazole, monomers and methods for their preparation, their use as semiconductors in organic electronic (OE) devices, especially in organic photovoltaic (OPV) devices, and to OE and OPV devices comprising these polymers.
摘要:
The invention concerns the production of poly(arylene-vinylenes) and related polymers whose polymerization is triggered photochemically. For that purpose, the low molecular starting materials are firstly cooled to temperatures which are so low that in fact their activation into mostly chinoid intermediate stages (the “active” monomer) occurs; the thermally induced polymerization, however, either does not occur or barely takes place at all. The polymerization is instead triggered in a separate step by means of electromagnetic radiation of a suitable wavelength—either using the absorption behavior of the low-molecular starting compounds/the monomers, or mediated by means of photoinitiators and/or sensitizers.By way of example, with this method a display is suitable to be coated with poly(arylene-vinylenes). The monomer is hereby deposited. The polymer is subsequently produced in a photo-induced manner. The remaining monomer is washed out. The process takes place at low temperatures.
