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.

Abstract: The present invention provides a product and a manufacturing process for an aqueous dispersible dendritic polymer with various functionalities, and polymer compositions and polymer formulations comprising such a dendritic polymer. The aqueous dispersible dendritic polymer composition comprises a hydrophilic functional group to allow dispersion in aqueous solvents and improve washability of the polymer, a low surface tension functional group to impart resistance to dirt pick-up and optionally, a curable functional group to allow superior cross-linking capabilities and optionally, a softening functional group to impart flexibility to the composition.
