DESIGN, SYNTHESIS AND EVALUATION OF ADVANCED TRANSPORT MATERIALS FOR ORGANIC ELECTRONICS

The development of new organic semiconducting materials for organic electronics has been the focus of considerable research in the past several years due to the promise of low cost, light weight, flexible, and portable electronic applications. To date, the most widely investigated organic semiconductors are p-type (hole transporting) materials, while the n-type materials get less attention due to the difficulties in synthesis. Recently, PHH molecules, because of the extended p-electronstructures, have received attention for their unusual (photo)-physical properties, for example, anomalous fluorescence and high electron affinities. In particular, anthracene based PHHs exhibit absorptions and electron affinities higher than the naphthalene and perylene analogues and play a significant role as n-type materials for organic electronics
