Organometallic polymers continue to attract much interest due to the unprecedented properties and novel applications in optoelectronic devices. Among the new materials developed, organoboron polymers are known for their intriguing electronic and photophysical properties, which have been exploited, for example, in the development of new linear and non-linear optical materials, emission and electron conduction layers in organic light emitting devices (OLEDs), and new probes and sensors for anions.
We have developed different modular routes for incorporation of electron-deficient boron centers into the main chain and side chain of thiophene-based polymers. The direct attachment of boron to the thiophene moieties provides for strong electronic effects of the boryl groups on the polymer itself. The photophysical properties, relative Lewis acidity, and environmental stability can all be fine-tuned by introducing suitable pendant aryl groups to the boron centers. The different polymer architectures will be compared with respect to their suitability as optoelectronic materials and as sensors for nucleophiles. Finally, the use of controlled polymerization techniques allows to realize more complex polymer architectures which can be exploited for the development of nanostructured materials.
