This compound is an axially chiral molecule formed by two naphthalene units directly connected through a single bond. The core electronic feature of this compound lies in the non-coplanar twisted conformation between the two naphthalene rings due to steric hindrance. This structure effectively suppresses strong π-π stacking between molecules, helping to reduce concentration quenching in the solid state. At the same time, the larger conjugated system of the naphthalene rings provides a narrower optical bandgap than that of a benzene ring, moderate charge transport ability, and good thermal stability. Its unique axial chirality also opens up possibilities for tuning the material's photophysical properties, such as circularly polarized luminescence.

In OLED applications, this compound and its derivatives mainly serve as an important multifunctional scaffold material. With its twisted molecular structure and extended conjugation, it is commonly used as a core unit for constructing efficient blue fluorescent materials and host materials (especially for phosphorescent devices). The derivatives can effectively balance exciton utilization and emission color purity, contributing to the improvement of device efficiency and stability. More importantly, its inherent chirality makes it an ideal platform for developing circularly polarized organic light-emitting diode (CP-OLED) materials, which has unique value for future 3D displays and spintronics applications.
