Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional compounds and polymers are used for charge transport, then basic charge transporting property is achieved, but ionization potential and mobility cannot be optimized for efficient electric device performance
Solution Approach 1:
The patent systematically varies structural parameters including aromatic groups (Ar1), substituent types (R1), and ring fusion patterns in thiazolothiazole compounds to optimize ionization potential and charge mobility. This parameter optimization enables tailored charge transporting properties for specific electric device applications while maintaining reliable charge transport function.
Solution Approach 2:
The invention creates composite molecular structures by combining thiazolothiazole core units with diverse aromatic groups and substituent patterns. These composite structures integrate multiple functional elements that work synergistically to achieve both efficient charge transport and optimized ionization potential, resolving the contradiction between performance reliability and adaptability.
2Reliability
If structural variations are introduced to optimize ionization potential and mobility, then charge transporting performance is improved, but synthesis complexity increases
Solution Approach 1:
The patent divides the complex thiazolothiazole molecular structure into modular components: a core thiazolothiazole unit, aromatic group substituents (Ar1), and variable substituent patterns (R1). This segmentation allows systematic optimization of ionization potential and mobility through controlled variation of individual modules while maintaining a standardized synthesis framework, thereby managing synthesis complexity.
Solution Approach 2:
The invention applies local quality variations by introducing specific aromatic groups and substituents at particular positions on the thiazolothiazole core structure. This localized modification approach enables precise control over ionization potential and charge mobility without requiring complete restructuring of the entire molecule, thus improving performance while limiting the increase in synthesis complexity to specific, manageable steps.
