Organic Semiconductor Transport Composition Without Post-Oxidation

The patent removes the problematic additives (LiTFSI and tBP) from the composition while maintaining the desired conductivity through alternative means. The core organic semiconductor material is used in its purified form without the unstable additive components, thereby eliminating moisture sensitivity and volatility issues while preserving electrical conductivity properties.

The patent performs the oxidation process in advance during the synthesis stage, creating pre-oxidized organic semiconductor materials before final device assembly. This preliminary oxidation eliminates the need for lengthy post-oxidation steps (10-24 hours) during device manufacturing, thereby significantly reducing production cycle time while ensuring the material has the required conductive properties ready for immediate use.

The oxidation process is completed during the initial material synthesis phase under controlled laboratory conditions, producing pre-oxidized organic semiconductor materials with stable conductive properties. This preliminary action transfers the complexity of environmental control to the material fabrication stage rather than the device manufacturing stage, allowing subsequent device assembly to proceed under simpler, less restrictive conditions while maintaining high conductivity.

The patent eliminates the reactive additives (LiTFSI and tBP) that generate impurities through side reactions. By using a simplified composition of pure organic semiconductor material with pre-established conductive properties, the method prevents the formation of reaction byproducts and impurities that would otherwise degrade device performance, thereby achieving high device efficiency without compromising conductivity.
