​The research in Al-Hashimi's group focuses on the synthesis of organic polymers in particular the "design and synthesis of organic semiconductor materials" for a range of optoelectronic applications, including field effect transistors, photovoltaic devices, light emitting diodes and sensors. This has made enormous scientific and commercial progress over the last 10 years, mainly driven by the potential of applications such as light-emitting diodes (OLEDS) for display and large area lighting, field effect transistors (OFETs) for flexible backplanes and e-paper and solar cells (OPV) for large area energy generation.

Other topics of interest center on: 

  • The development of well-defined novel polymeric materials for Ring Opening Metathesis Polymerisation (ROMP) and Ring closing Metathesis (RCM).
  • Synthesis of recoverable, reusable homogeneous and heterogeneous catalysts.
