NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of material innovation, particularly in the rapidly evolving field of organic light-emitting diodes (OLEDs). Our focus on advanced materials, such as those enabling high efficiency white OLEDs, is shaping the future of illumination and display technology. The introduction of Thermally Activated Delayed Fluorescence (TADF) materials has been a pivotal development, allowing for the theoretical harvesting of 100% of electrogenerated excitons. This is achieved through a process known as reverse intersystem crossing (RISC) from the triplet excited state back to the singlet excited state, a feat made possible by a small energy gap between the singlet and triplet states (ΔEST).

The scientific community has witnessed remarkable progress, with the external quantum efficiency (EQE) of monochromatic OLEDs based on TADF emitters consistently surpassing 30% and even approaching 40% in recent studies. This impressive performance, coupled with the competitive pricing of many TADF materials, positions them as strong successors to traditional phosphorescence materials in the OLED industry. At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to supplying these advanced materials to researchers and manufacturers seeking to push the boundaries of OLED performance.

A key area of advancement is in the development of high efficiency white OLEDs (WOLEDs). Achieving high power efficiency (PE) and mitigating efficiency roll-off are crucial for the commercialization of WOLEDs, especially for energy conservation. Our research and product offerings are centered around materials and device architectures that address these challenges. For instance, the exploration of sandwich configurations and interlayer sensitization techniques, utilizing materials like 4CzTPNBu, has led to record-breaking PEs exceeding 130 lm W⁻¹ for two-color WOLEDs and over 100 lm W⁻¹ for three-color WOLEDs. These advancements are crucial for creating practical, energy-saving illumination and display solutions. The ability to buy these innovative materials is now more accessible, supporting the ongoing research and development in this dynamic sector.

The development of efficient WOLEDs also hinges on carefully selecting host materials that can facilitate efficient energy transfer and charge transport. The properties of these host materials, such as their HOMO/LUMO levels, triplet energy, and thermal stability, play a critical role. By understanding and manipulating these parameters, NINGBO INNO PHARMCHEM CO.,LTD. provides materials that enable the creation of robust and efficient OLED devices. Whether you are looking for TADF emitters, host materials, or other specialized OLED components, our commitment to quality and innovation ensures that you have access to the materials needed to drive the next generation of lighting and display technology.
