POLY 449 |
| Polythiophenes are one of the most intensely studied classes of conjugated polymers due to their advantageous optical and electronic properties. Diarylboryl side chain modified polythiophenes have been synthesized by a post polymer modification methodology that involves silicon-boron exchange. The progress of the reaction of the silylated polythiophene with BBr3 can be monitored by the disappearance of the signals of the trimethylsilyl groups in the 1H and 29Si NMR spectra, and the appearance of the new signals in the 11B NMR. Compared to main chain boron containing polythiophenes, diarylboryl substituted polythiophenes provide additional synthetic flexibility. The optical and electronic properties of the new polymers have been investigated. |
