At NINGBO INNO PHARMCHEM CO.,LTD., our work extends beyond simply supplying chemicals; we are deeply invested in understanding the fundamental science that governs their performance, particularly in the realm of advanced organic electronics. A prime example is our focus on N,N'-Bis[4-(diphenylamino)phenyl]-N,N'-di-1-naphthalenyl-[1,1'-biphenyl]-4,4'-diamine, an organic semiconductor whose efficacy in OLEDs is directly tied to its intricate molecular structure.

The molecule's design features a central biphenyl core, flanked by extensive triarylamine units, each terminated with diphenylamine groups and naphthalene moieties. This specific arrangement is not accidental; it is engineered to optimize key electronic and physical properties. For instance, the propeller-like conformation of the triarylamine units, as revealed by quantum chemical modeling, influences pi-orbital overlap and intermolecular stacking in thin films. This packing directly impacts charge carrier mobility, a critical parameter for efficient charge transport in OLEDs.

The energy levels of the molecule, specifically its HOMO (Highest Occupied Molecular Orbital) and LUMO (Lowest Unoccupied Molecular Orbital), are crucial for its function as a hole transport material. Density Functional Theory (DFT) calculations help us predict and verify these energy levels. A well-aligned HOMO level with the anode material is essential for minimizing injection barriers, and a suitable LUMO level helps confine electrons within the emissive layer, preventing unwanted recombination and enhancing device efficiency. We actively investigate how variations in synthesis and purification affect these crucial energy levels.

Furthermore, the molecule's internal reorganization energy, a measure of how much the molecular geometry changes upon ionization or electron capture, also plays a significant role in charge transport. Lower reorganization energies generally lead to higher charge mobility. Our research, employing methods like the adiabatic potential method, aims to quantify and understand these energies to further optimize the material's performance. The price of such high-performance materials is justified by their ability to enable more efficient and durable electronic devices.
