Acenes, such as aza-acenes are attractive materials for organic semiconductors, specifically for n-type materials. There are disclosed new derivatives of acenes that are fabricated using novel synthesis. For example, the disclosed fabrication strategies have allowed for the first time new aza-tetracene and aza-pentacene derivatives. The HOMO and LUMO energy levels of these materials are tunable through appropriate substitution and as predicted, deepened. There are also disclosed organic photosensitive devices comprising at least one aza-acene such as aza-tetracene and aza-pentacene.

Synthesis of aza-acenes as novel n-type materials for organic electronics

Disclosed herein are stable organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material having a sufficiently high glass transition temperature, e.g., higher than the temperature or temperature range at which the device typically operates, higher than a highest operating temperature of the device, higher than a threshold temperature value, etc. and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).
