摘要

•A well-crystallized hydrazine-linked COF (Tf-DHzOH) was synthesized successfully from 2,5-dihydroxyterephtalohydrazide and 1,3,5-triformyl-benzene.•Tf-DHzOH COF was firstly regarded as a stationary phase material to prepare coated capillary column for open-tubular capillary electrochromatography (OT-CEC).•The separation abilities of Tf-DHzOH coated OT-CEC were evaluated by considering five amino acids, nine sulfonamides and four tetracyclines as analytes.
