Title: | Low-band-gap conjugated polymers - Improved model compounds for the structural-analysis of poly(isothianaphthene) | Authors: | KIEBOOMS, Rafael HOOGMARTENS, I ADRIAENSENS, Peter VANDERZANDE, Dirk GELAN, Jan |
Issue Date: | 1995 | Publisher: | AMER CHEMICAL SOC | Source: | MACROMOLECULES, 28(14). p. 4961-4969 | Abstract: | The simulation of the structure of aromatic and quinoid poly(isothianaphthene) (PITN) has been improved, by the synthesis of new model compounds. The C-13 NMR investigation confirms our previous results that the geometric structure of this low-band-gap conducting polymer shows a strong quinoid character. For the aromatic structure, 1,3-dithienylisothianaphthene and a series of disilylated isothianaphthene oligomers were synthesized. trans-3,3'-Bibenzo[c]thienylidene was prepared in order to model the quinoid structure. All these new model compounds simulate better neighboring S-atom effects, a structural feature which was not accounted for in the previously reported model compounds. | Notes: | LIMBURGS UNIV CENTRUM,DIV CHEM,INST MAT RES,B-3590 DIEPENBEEK,BELGIUM. | Document URI: | http://hdl.handle.net/1942/3568 | DOI: | 10.1021/ma00118a025 | ISI #: | A1995RH91600025 | Type: | Journal Contribution |
