[Preparation of boronate affinity monolithic column with high specific surface using highly structurally symmetrical...

Area of Science:

• Chromatography
• Materials Science
• Analytical Chemistry

Context:

• Boronate affinity monolithic columns are crucial for isolating cis-diol containing compounds.
• Controlling the micro-structure of monolithic capillaries during preparation is challenging.
• Existing methods often lack high specific surface area and optimal binding pH.

Purpose:

• To prepare a novel boronate affinity monolithic capillary with enhanced specific surface area.
• To achieve selective isolation of cis-diol containing compounds under neutral pH conditions.
• To overcome limitations in controlling micro-structure during monolithic column preparation.

Summary:

• A boronate affinity monolithic capillary was synthesized using in-situ polymerization with highly symmetrical copolymerizing reagents, melamine and tris(2,3-epoxypropyl) isocyanurate (TEPIC).
• The "teamed boronate affinity" principle facilitated a decrease in binding pH to the neutral range.
• The resulting monolithic capillary exhibited a significantly increased specific surface area (80.3 m²/g) compared to previously reported materials.

Impact:

• Provides a superior chromatographic medium for the selective isolation of cis-diol containing compounds.
• The high specific surface area enhances isolation efficiency and capacity.
• The neutral binding pH expands the applicability of boronate affinity chromatography to a wider range of samples.
