Anthrone Heterocycle OLED Materials for Efficiency and Lifetime

The patent modifies the molecular structure parameters of OLED functional materials by introducing anthrone and N-containing heterocycle groups, adjusting HOMO/LUMO energy levels, and optimizing molecular weight and glass transition temperature to simultaneously improve luminous efficiency and service life

The patent creates composite organic functional materials by combining anthrone core structures with N-containing heterocycle units (such as triazole, tetrazole, imidazole rings), forming new compounds with synergistic effects that enhance both efficiency and reliability

The patent divides the organic functional material into distinct functional segments: anthrone core providing thermal stability, N-containing heterocycle units providing electron transport capability, and adjustable aromatic substituents for energy level tuning, allowing independent optimization of each segment

The patent designs compounds that can serve multiple functions within the OLED structure, such as acting as both host material and electron transport material, or as interface layer material with both protection and charge transport capabilities, reducing the need for multiple specialized materials

The patent optimizes molecular parameters including HOMO/LUMO energy level differences, glass transition temperature, and carrier mobility to enhance electron-hole recombination efficiency and reduce energy loss, directly improving both luminous and power efficiency

The patent converts potential harmful effects such as non-radiative recombination and energy loss into beneficial outcomes by designing molecules with optimized energy level alignments that guide energy flow toward radiative recombination, and using thermal stability to prevent degradation that would otherwise reduce efficiency
