| Abstract: γ-CD-MOFs were synthesized with γ-cyclodextrin (γ-CD), potassium hydroxide, methanol, and water, whose structure, stability, and morphology were characterized by X-ray diffraction, thermogravimetric analysis, and scanning electron microscope. Due to γ-CD-MOFs having a 1D channel, rhodamine 6G (R6G) with yellow light emission was introduced into the channel, to obtain a fluorescent composite R6G@γ-CD-MOFs and its fluorescence response to different metal ions was explored. The experimental results show that R6G@γ-CD-MOFs can selectively sense Fe3+ ions from 12 kinds of metal ions, and its fluorescence quenching constant (Ksv) was 1.03×104 L·mol-1 in a range of 2×10-4-2.0×10-2 mol·L-1. |
