1Reliability
If existing compounds are used for controlling harmful arthropods, then basic control function is provided, but control efficacy is limited
Solution Approach 1:
The patent applies parameter changes by systematically varying chemical structure parameters of the heterocyclic compounds. Specifically, different substituent groups (R1-R6, R8-R16) are introduced at various positions on the core heterocyclic ring structure, and different heteroatom combinations (Z1-Z6 representing O, S, or NH) are explored to optimize biological activity and broaden spectrum of control against harmful arthropods
Solution Approach 2:
The patent employs composite materials principle by creating heterocyclic compounds with multiple functional groups and heteroatoms integrated into a single molecular framework. The compounds combine nitrogen, oxygen, and/or sulfur atoms within the ring structure along with various substituent groups to achieve enhanced and diversified arthropod control efficacy
