Multiple Resonance OLED Compound Design

The patent systematically varies structural parameters of compounds with multiple resonance effects, including substituent types at different positions, ring skeleton configurations, and molecular symmetry. By changing these parameters and measuring corresponding light emission characteristics (quantum efficiency, FWHM, color coordinates), the patent establishes structure-property relationships that guide material design for OLEDs

The patent divides the complex structure-light emission relationship into manageable segments by analyzing specific structural features independently: substituent effects at R1-R6 positions, core skeleton variations, and molecular symmetry elements. This segmented approach allows systematic understanding of how each structural component contributes to overall light emission performance

The patent performs preliminary computational analysis and theoretical predictions about structure-light emission relationships before synthesizing new compounds. By using density functional theory (DFT) calculations to predict HOMO-LUMO energy gaps, excited state lifetimes, and emission wavelengths, the patent prioritizes synthesis of compounds most likely to exhibit desired properties, reducing wasted development time on unpromising candidates

The patent uses established structure-property relationships to directly design new ring skeleton structures with target properties. By adjusting known structural parameters (substituent types, positions, and combinations) based on predicted performance, the patent accelerates material development without requiring extensive trial-and-error synthesis of completely novel structures
