Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional organic compounds are used in opto-electronic devices, then the device structure can be implemented, but deposition stability and heat resistance are insufficient
Solution Approach 1:
The patent modifies the molecular structure of organic compounds by introducing specific heteroarylene groups and adjusting structural parameters (Formula 1 with specific Ar3, L1, L2, CY1, CY2 groups) to simultaneously improve deposition stability and heat resistance. This structural parameter optimization allows the compound to maintain both reliability during deposition and thermal stability during operation.
Solution Approach 2:
The invention uses composite organic compound structures combining electron-donating groups, electron-accepting groups, and conjugation groups in a specific molecular architecture. This composite molecular design creates a material that exhibits both excellent deposition stability and superior heat resistance, resolving the contradiction between these two properties.
