Synthesis of spiro borate-linked covalent organic frameworks (COFs) based on 1,3-diol borates

Key Points

• The aim is to synthesize and characterize new spiro borate-linked covalent organic frameworks.
• Synthesis of BSCOF-1 and BSCOF-2 using 1,3-diol borates
• Characterization performed using PXRD, FT-IR, solid-state ¹¹B NMR, and XPS
• N₂ sorption measurements conducted to assess porosity and surface area
• Both COFs showed structural integrity and unique properties
• Enhanced porosity was observed in BSCOF-1 and BSCOF-2
• Characterization techniques confirmed successful synthesis and structure
