Abstract
Crystallinity, stability, and complexity are significant factors to consider in the design and development of covalent organic frameworks (COFs). Among various building blocks used, 1,3,5-triformylphloroglucinol (Tp) is notable for enhancing both crystallinity and structural stability in COFs. Tp facilitates the formation of β-ketoenamine-linked COFs through keto-enol tautomerism when reacted with aromatic amines. This review article examines the stability, crystallinity, and flexibility of synthetic methodologies involving Tp-based COFs, while highlighting their recent applications. We emphasize the critical roles of non-covalent interactions and keto-enol tautomerism in achieving high levels of crystallinity and stability. Additionally, the diverse and straightforward synthesis methods available for Tp-based COFs contribute to the prevalence of 1,3,5-triformylphloroglucinol in COF development. We conclude by addressing the challenges and future prospects in this area, underscoring the significant potential of Tp-based COFs for environmental and energy-related applications due to their exceptional structural tunability and functionality.
