Transformation of Covalent Organic Framework from Dual Pores to Single Pores and Their Different Properties
Abstract
We have achieved a controllable transformation of covalent organic framework (COF) isomers from BATD-Dma-COF-K (dual pores) to BATD-Dma-COF-R (single pores). The fluorescence of BATD-Dma-COF-K was enhanced by clinafloxacin (CFN). After transformation from dual pores to single pores, BATD-Dma-COF-R can effectively adsorb CFN, but cannot fluoresce to detect CFN.
