Advantages

Fast response

Fluorescence response time for all analytes is less than 20 s, suitable for rapid detection.

Applications

• fluorescence sensing：Rapid fluorescence detection of multiple hazardous species in aqueous media.
• hazardous ion detection：Specifically recognizes hazardous ions such as Fe³⁺, CrO₄²⁻, Cr₂O₇²⁻.
• CO₂ cycloaddition：Converts CO₂ to cyclic carbonates under mild conditions.
• coordination polymers：Provides a water-stable bifunctional platform.
• MOF catalysis：Utilizes Lewis acid-base sites for cycloaddition catalysis.
