摘要： Thin films of organic semiconducting material comprising perylene diimide small molecules with pyrrolic N—H bonds. Films are prepared using green solvents including water and alcohols. The films can be solvent-resistant and generally range in thickness from 10 to 1000 nm. Perylene diimide molecules are dissolved in solvent by addition of a base to polarize the pyrrolic N—H bond believed to generate an ionic salt in alcohol or aqueous solution. Devices containing such films are provided. Methods of making films and methods of using films in OPV device applications and in amine sensors are provided.

摘要： Oligomeric compounds useful as organic conjugated materials in electronic devices. Oligomeric compounds contain three or more or four or more of certain PDI units bonded to an organic core. The organic core contains one, two or more thiophene rings. The organic core can contain two or more thiophene rings separated by a linker group; two or more thiophene rings directly fused to each other or indirectly fused to each other through an optionally substituted aromatic or non-aromatic carbocylic ring system or an optionally substituted aromatic heterocyclic or non-aromatic heterocyclic ring system; or each of two or more thiophene rings is fused to an aromatic or non-aromatic carbocylic ring system or an aromatic heterocyclic or non-aromatic heterocyclic ring system and the resulting fused rings containing a thiophene ring are each separated by a linker group M. Methods for making oligomeric compounds by direct heteroarylation are provided.

摘要： Multilayer organic electronic devices having an electron transport layer (ETL). The ETL is a film comprising an N-annulated perylene diimide (NPDI) compound having at least one pyrrole N—H bond and at least 1 equivalent of Cs2CO3 with respect to the NPDI compound and the number of pyrrolic N—H bonds in the NPDI compound. The ETL is positioned between the photoactive layer and the top electrode (cathode). Multilayer devices including the ETL are fabricated employing immiscible solvent methods. A method for making the ETL layers is provided which employs an ink formulation in which the NPDI compound is solubilized in a selected polar solvent by addition of at least one equivalent of Cs2CO3 respect to the NPDI compound. Exemplary polar solvents include ethanol, 1-propanol, ethyl acetate and mixtures thereof.
