  1. Development of Polymer Systems with High Electron Mobility for Photovoltaic Applications Jie Hu, Dong Zhang, Shi Jin, Stephen Z.D. Cheng and Frank W. Harris The Maurice Morton Institute of Polymer Science The University of Akron Akron, OH 44325-3909

  2. Objective To develop materials with high electron mobility for photovoltaic applications

  3. Approach Utilization of nitrogen-containing heterocyclic structures Poly(quinoxalines) Poly(pyridinium salts)

  4. Discotic Liquid Cyrstalline Compounds Discotic liquid crystalline compounds have been prepared that exhibit high hole mobilities. Specific objective of this work is to develop discotic/planar liquid crystalline compounds that display high electron mobilities. Adam, D.; Schumacher, P.; Simmerer, J.; Haussling, L.; Siemersmeyer, K.; Etzbach, K.H.; Ringsdorf, H.; Haarer, D. Nature 1994, 371, 141.

  5. Preparation of Target Compounds

  6. Synthesis of 4,5,9,10-Tetraone Pyrene

  7. Synthesis of 4,5-Diamino-1,2-bisalkoxy Benzenes

  8. Phase Transition Compounds of 3a-e 213 268 210 234 202 > 350 316 The transition temperatures (°C) were determined by DSC at 10 °C/min, the phase types were suggested by PLM and WAXD.

  9. PLM Micrograph of 3a 100 m The picture was taken at 261oC cooling from the isotropic phase

  10. Current Work Structural modifications to lower transition temperatures and increase electron affinity.
