Title: | Characterization of poly(isothianaphthene) derivatives and analogs by using solid-state C-13 NMR | Authors: | OTTENBOURGS, Benjamin PAULUSSEN, Harald ADRIAENSENS, Peter VANDERZANDE, Dirk GELAN, Jan |
Issue Date: | 1997 | Publisher: | ELSEVIER SCIENCE SA LAUSANNE | Source: | SYNTHETIC METALS, 89(2). p. 95-102 | Abstract: | The combination of several options of a multipurpose C-13 CP/MAS solid-state pulse sequence allows the characterization of insoluble poly(isothianaphthene) (PITN) derivatives and analogs. In order to improve solubility and processability of low bandgap polymers, poly(5-tert.butylisothianaphthene) and poly(5,6-dihexoxyisothianaphthene) have been synthesized and analyzed. The same chemistry also allows for the synthesis of poly(2,3-dihydro-1H-indene) and poly(isoindole). Based on model compounds, a proper C-13 NMR assignment enables one to predict the geometric structure (aromatic versus quinoid) of these conducting polymers.
