The field of organic electronics is rapidly advancing, driven by the development of sophisticated materials that enable unprecedented device performance. Among these, Thermally Activated Delayed Fluorescence (TADF) emitters have become central to achieving highly efficient and color-pure Organic Light-Emitting Diodes (OLEDs). This article focuses on 4CzIPN-tBu (CAS 1630263-99-8), a prominent TADF material, exploring its chemical structure, optoelectronic properties, applications, and the importance of reliable sourcing from a dedicated manufacturer.

Chemical Structure and TADF Mechanism of 4CzIPN-tBu

4CzIPN-tBu, chemically known as 2,4,5,6-Tetrakis(3,6-di-tert-butylcarbazol-9-yl)-1,3-dicyanobenzene, is a donor-acceptor type molecule. Its core structure features a dicyanobenzene unit surrounded by tert-butyl-substituted carbazole groups. This arrangement is crucial for its TADF properties. The tert-butyl groups enhance the electron-donating strength of the carbazole units, influencing the donor-acceptor interaction. Crucially, these bulky groups also introduce steric hindrance, minimizing intermolecular interactions. This steric effect is key to preventing aggregation and ensuring efficient reverse intersystem crossing (RISC), the process that underlies TADF emission.

The photophysical properties of 4CzIPN-tBu are noteworthy: it exhibits absorption at 389 nm and photoluminescence emission at 550 nm in film. Its HOMO level is reported at 5.70 eV and LUMO at 3.30 eV, facilitating effective charge injection and transport within OLED devices. As a leading supplier, we ensure that the 4CzIPN-tBu we provide maintains these precise characteristics.

Key Applications of 4CzIPN-tBu

  • OLEDs: 4CzIPN-tBu is widely utilized as a yellow dopant and an assistant host in OLEDs. It plays a vital role in achieving high external quantum efficiencies (EQEs), with devices demonstrating up to 15.3% EQE when paired with specific fluorescent emitters. Its function as an assistant host significantly reduces triplet exciton loss by spatially separating molecules, thereby boosting overall device performance and stability.
  • Photocatalysis: Beyond optoelectronics, 4CzIPN-tBu has shown promise as a photocatalyst. Its ability to facilitate proton-coupled electron transfer reactions makes it a valuable compound for research in sustainable chemistry and energy conversion.
