Artificial intelligence (AI) is profoundly reshaping the discovery and design of organic light-emitting diode (OLED) materials, shifting conventional intuition-driven development into an integrated, data-driven paradigm. The increasing demand for high-performance OLED emitters with ultra-narrow emission spectrum and enhanced operational stability has highlighted the urgent need for a dedicated, multi-scale computational framework tailored to OLED-specific challenges. This review proposes a systematic AI-driven framework that combines quantum chemistry calculations, property prediction models, and generative algorithms to enable high-throughput screening and inverse design workflows for organic luminescent materials. Each component is critically analyzed in terms of theoretical underpinnings, practical benefits, inherent limitations, and avenues for further optimization. By presenting detailed case studies, we elucidate how AI approaches can tackle key bottlenecks in OLED material discovery and development. Moreover, we highlight essential future directions, including the integration of domain-specific expertise, the establishment of high-quality experimentally validated datasets, and the creation of molecular generation models specifically adapted for luminescent materials. Overall, this review aims to provide a comprehensive roadmap for advancing AI-guided materials research, offering transferable insights that extend beyond OLEDs to a broad range of organic optoelectronic materials.

As a class of functional materials used in organic light-emitting diodes (OLEDs), sensitizers play a crucial role in the improvement of device efficiency, color purity, and stability. In recent years, thermally activated delayed fluorescence (TADF) sensitizers have attracted much attention mainly because of their high exciton utilization efficiency by converting quenched triplet excitons into singlet excitons. Despite the experimental success of sensitization strategies in enhancing OLED performance, the lack of theoretical models for sensitizers continues to hinder further development.

The organic light-emitting diode (OLED) performance of multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters is fundamentally constrained by their slow reverse intersystem crossing (RISC) and pronounced aggregation-caused quenching (ACQ). Herein, through regioselective borylation, we design and synthesize a series of blue MR-TADF emitters. The regioisomerization-directed twist configuration synergistically enhances RISC while suppressing ACQ, without compromising spectral purity.

The effect that permanent spontaneous orientation polarization can have on the performance of an organic light-emitting diode device has received limited attention in recent years and is commonly overlooked. While studies have shown that polarized layers can lead to lower operating voltages due to higher densities of mobile charge carriers, the undesirable reduction of efficiency due to quenching of excitons is also commonly observed. From this perspective, we explore device architectures that utilize molecules that form layers with substantial polarization and use simulation methods to predict the degree of polarization.

Copper-based organic light-emitting diodes (OLEDs) are low-cost alternatives to precious metal-based OLEDs, but currently no such OLEDs can meet the practical requirements for high colour purity, device efficiency, and operational stability. Carbene-Cu(I)-amide emitters reported here exhibited thermally activated delayed fluorescent emission with quantum efficiencies up to 0.90 and radiative decay rates of 2.

The development of efficient and stable ultra-narrowband pure-blue multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters is critical for next-generation wide-gamut OLED displays. Herein, we present a molecular design strategy that enhances emitter stability and efficiency by reinforcing the weak C─N bonds through selective incorporation of heterocyclic carbazole (Cz) units into the MR framework. Two proof-of-concept emitters, m-Cz-DABNA and tBu-Cz-DABNA, were synthesized via high-yield, lithium-free borylation.
