Recently, there has been a great deal of Interest In semiconducting organic polymers, particularly polyacetylene ((CH) ), as electronic materials for applications where low cost and large area are important. This report first discusses the potential of organic polymer semiconductors to meet the electronic, physical and economic constraints Imposed by the photovoltaic application. Then, recent results on the structural, electrical, and optical properties of one candidate material, polyacrylonitrile (PAN), are presented. Areas for further Investigation are Indicated.

We now discuss the role of supramolecular structure for more specific applications. In particular, we focus our attention to transport properties (both for metallic and semiconducting polymers), sensors, LEDs, transistors, photovoltaic cells, and Anally, to the integration into microdevices. 

Nanostructured semiconducting block copolymers containing triphenylamine as hole transport moiety and perylene bisimide as dye and electron transport, have been investigated in view of applications in photovoltaic devices. The polymers show nanowire like structure which formation is driven by the crystallization of perylene bisimides via n- n stacking and since this self-assembly gives rise to domains size comparable to the exciton diffusion length, these materials offer perspectives for the implementation of organic solar cells [357].
