“…Bian et al designed and synthesized a novel covalent organic skeleton (M-TT-COF) [ 41 ]. As an “turn on” fluorescence sensor, M-TT-COF can continuously and selectively identify and detect Eu 3+ and tetracycline antibiotics, while other metal ions, anions and antibiotics have no significant effect on selective detection performance.…”
