A functionalized metallacage with anthracene groups was synthesized and analyzed using various techniques including UV/vis spectroscopy, NMR, ESI-TOF mass spectrometry, and X-ray single crystal diffraction. This metallacage showed specific fluorescence enhancement response to OH-, PO43-, and AcO- anions, which was attributed to the disassembly of the metallacage induced by these anions.
Functionalized metallacages have attracted tremendous attention in recent years due to their potential applications in optical sensing, catalysis, and recognition. A novel anthracene-functionalized metallacage was synthesized and characterized in detail by UV/vis spectroscopy, 1D/2D NMR, electrospray ionization time-of-flight mass spectrometry, and X-ray single crystal diffraction. This metallacage exhibited a specific fluorescence enhancement response to OH-, PO43-, and AcO- anions, and further analysis indicated that this was due to anion induced metallacage disassembly.
