Abstract
Covalent Organic
Frameworks (COFs) represent a new category of crystalline porous materials
characterized by adjustable structures and remarkable stability, making them
suitable for various uses such as gas storage, catalysis, electronics, and
environmental cleanup. However, traditional COFs often encounter issues related
to stability, functionality, and scalability. Recently, four-arm polycyclic
aromatic hydrocarbons (4-PAHs) have been identified as highly effective
components for COF synthesis due to their rigid, π-conjugated structures and
symmetrical shapes. This study examines how 4-PAHs contribute to improving the
structural integrity, thermal and chemical resistance, and functional
capabilities of COFs. Comparative studies reveal notable enhancements in
decomposition temperatures (exceeding 450°C), chemical resilience in acidic and
basic environments, and functional parameters like CO₂ adsorption, catalytic
turnover frequency, and charge transport. Additionally, the π–π stacking
interactions inherent in 4-PAHs enhance electron delocalization and molecular
interactions, broadening COF applications in optoelectronics and sensing.
Nonetheless, challenges persist, such as inconsistencies in testing methods, a
lack of long-term stability data, and scalability issues. The findings
emphasize the need to combine computational modelling with experimental
validation to guide the development of next-generation COFs, highlighting the
crucial role of 4-PAHs in creating robust, multifunctional frameworks suitable
for industrial and environmental applications.
