Perimidine Derivatives and Use Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a class of chemical compounds called perimidine derivatives, specifically designed for use in organic electronic devices. These derivatives, which can take various forms (cations, zwitterions, their dimers, dications, and oligomers), are uncommonly stable against air and water. The invention uses these perimidine derivatives primarily as n-type dopants for organic semiconductors, especially in the electron transport layers or as charge injection layers in electronic or optoelectronic components. Their robust stability and doping efficiency make them highly promising for applications that require reliable electrical performance over time.

Use CasesContent extracted from patent full text and abstract with AI.

• As n-type dopants in organic semiconductors to increase electrical conductivity.
• In the electron transport layers (ETL) of organic light emitting diodes (OLEDs) to improve device efficiency and lifetime.
• For doping charge carrier injection layers in organic photovoltaic cells (solar cells), organic field-effect transistors (OFETs), and dye-sensitized solar cells (DSSCs).
• In the production of organic electronic and optoelectronic devices such as displays, sensors, and circuits.
• As electrode materials or active components in batteries, accumulators, and capacitors.
• For improved electrical performance in thermoelectric generators and data storage devices.

BenefitsContent extracted from patent full text and abstract with AI.

• High doping efficiency, enabling significant increases in conductivity of organic semiconducting materials.
• Exceptional stability against air and moisture, reducing degradation and enabling easier processing and storage.
• Lower diffusion into adjacent layers, resulting in longer device lifetime and more reliable electronic performance.
• Versatility in synthesis, allowing tunable properties by modifying substituents and molecular structure.
• Compatiblity with existing vacuum deposition and solution processing methods for device fabrication.
• Reduced contamination risk during manufacturing, as the dimers generate dopants without side-products that could affect device performance.
