Here’s PatSnap Eureka !
Summary
Problems
There is a continuous demand for improving the performance, lifespan, and efficiency of organic light emitting devices, particularly in the development of materials for their thin films to enhance their light emitting capabilities and operational stability.
Innovation solutions
A novel hetero-cyclic compound is introduced, represented by Chemical Formula 1, which can be used as a material for organic material layers in organic light emitting devices, specifically as an electron transport layer, hole blocking layer, or light emitting layer, due to its structural characteristics and substituent groups, enabling efficient light emission and transport of charge carriers.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If conventional organic thin film materials are used, then the device structure is simple, but the light emitting capability and operational stability are insufficient
Why choose this principle:
The patent modifies the molecular structure parameters of organic compounds by introducing specific heterocyclic groups (triazine, pyrimidine, pyridine rings) and substituent patterns to optimize electronic properties including HOMO/LUMO energy levels, charge mobility, and thermal stability, thereby improving operational stability while maintaining reasonable structural complexity
Principle concept:
If conventional organic thin film materials are used, then the device structure is simple, but the light emitting capability and operational stability are insufficient
Why choose this principle:
The invention employs composite molecular designs combining multiple heterocyclic units (e.g., carbazole + triazine, dibenzofuran + pyrimidine) to create materials with synergistic properties that simultaneously enhance charge transport, light emission, and device stability without excessive structural complexity
