Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional organic compounds are used in light-emitting elements, then the basic light emission function is achieved, but the efficiency, reliability, and operating voltage are insufficient
Solution Approach 1:
The patent modifies the molecular structure of organic compounds by changing chemical parameters - specifically incorporating benzofuropyrazine or benzothienopyrazine skeletons with aromatic or heteroaromatic ring substituents. This structural parameter change enhances both the reliability and emission efficiency simultaneously, resolving the contradiction between these two performance aspects.
Solution Approach 2:
The invention uses composite organic compounds combining specific heteroaromatic skeleton (benzofuropyrazine/benzothienopyrazine) with aromatic or heteroaromatic ring substituents. This composite molecular structure creates synergistic effects that improve both reliability and emission efficiency together, rather than treating them as separate optimization targets.
2Power
If conventional organic compounds are used, then the light-emitting element can operate, but the operating voltage is high
Solution Approach 1:
The patent changes the electronic structure parameters of the organic compound by introducing the benzofuropyrazine or benzothienopyrazine skeleton with aromatic/heteroaromatic substituents. This parameter change optimizes the energy levels and electron transport properties, enabling low voltage operation while maintaining high reliability.
3Duration of action of stationary object
If simple organic compounds are used, then the manufacturing is easier, but the lifetime and performance characteristics are insufficient
Solution Approach 1:
The invention systematically modifies molecular parameters by substituting aromatic or heteroaromatic rings at specific positions of the benzofuropyrazine/benzothienopyrazine skeleton. This controlled parameter change extends element lifetime while keeping the synthesis pathway manageable through established organic chemistry transformations.
Solution Approach 2:
The complex organic compound is segmented into functional modules: the core benzofuropyrazine/benzothienopyrazine skeleton providing structural stability and the aromatic/heteroaromatic substituents providing electronic properties. This modular segmentation allows for systematic optimization of lifetime and performance characteristics.

Implementation Method 1
Light-emitting elements (organic EL elements) including organic compounds and utilizing electroluminescence (EL) have been put to more practical use. Carriers are injected by application of voltage to the element, and light emission can be obtained from the light-emitting material by using the recombination energy of the carriers.
