NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying advanced chemical materials, and among them, 4,5-bis(carbazol-9-yl)-1,2-dicyanobenzene (2CzPN) holds a prominent position due to its exceptional characteristics for the organic electronics industry. This compound, with CAS number 1416881-50-9, is a vital component in the development of high-performance OLED devices, particularly as a Thermally Activated Delayed Fluorescence (TADF) emitter.

Chemically, 2CzPN is characterized by its molecular formula C32H18N4 and a molecular weight of 458.51 g/mol. Its structure is defined by two electron-donating carbazolyl groups attached to an electron-withdrawing 1,2-dicyanobenzene core. This molecular architecture is crucial for its function as a TADF material. The steric hindrance between the carbazolyl units and the dicyanobenzene ring causes a distortion from planarity, leading to a small singlet-triplet energy gap (ΔEST) of approximately 0.09 eV. This small gap facilitates efficient energy transfer from triplet excitons back to the singlet state, thereby enhancing electroluminescence efficiency.

The physical properties of 2CzPN, such as its appearance as a pale yellow crystalline powder, are consistent across various reputable suppliers. Its solubility in common organic solvents like chloroform and THF makes it amenable to solution processing techniques, which are often preferred for manufacturing large-area electronic devices. NINGBO INNO PHARMCHEM CO.,LTD. ensures that the 2CzPN we supply meets stringent purity standards, often exceeding 99% (HPLC) and can be provided in sublimed form, further guaranteeing its suitability for demanding electronic applications where impurities can significantly degrade device performance.

The primary application of 2CzPN lies in its use as an efficient sky-blue emitter in OLEDs. However, its utility extends to other areas within optoelectronics. Researchers are exploring its potential to improve the performance of small molecule organic solar cells by acting as a luminescent sensitizer. This dual functionality highlights the versatility of 2CzPN as a cutting-edge material. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing researchers and manufacturers with the high-quality 2CzPN they need to drive innovation in these fields. Our understanding of these chemical properties and application requirements ensures that we can offer tailored solutions and expert advice to our clients, supporting their R&D efforts and production needs effectively.
