Abstract: The invention provides for polymer structures and their preparation and resulting novel functionalities including open-shell character and high intrinsic conductivity with wide-range tenability. Electrical conductivity can be further modulated by introducing or blending with materials, fillers, dopants, and/or additives. The materials or resultant composites of the invention can be processed by various techniques into different forms to realize multiple applications.

Abstract: The present invention relates to a photodetector and methods for making a photodetector configured for converting light to an electronic signal. The photodetector includes a substrate containing a hole transport component and electron transport component; one or more photoactive layers including one or more semiconducting materials that comprise a photoactive small molecule, oligomeric, or polymeric electron donor and an electron acceptor, wherein the electron donor has a narrow bandgap of less than 1.4 eV; and one or more insulating materials, wherein the one or more semiconducting materials and the one or more insulating materials are present in a weight ratio of 1:0.1 to about 1:100; a cathode in electrical contact with the electron or hole transport component; and an anode in electrical contact with the hole or electron transport component.
