In supramolecular coordination chemistry field, coordination driven assembly of Metal-Organic Cages (MOCs) with well-defined shapes and unique cavities has drawn great attention in the past decades. A wide variety of applications, such as altering chemical reactivity, intriguing host-guest properties and potentials in chiral recognition, catalysis, as well as drug delivery and release have been thoroughly explored. In the present study, we have reported the host-guest and photochemistry study of ferrocene derivative guests, employing our MOC-16 as a host. The host-guest interaction of three ferrocene (Fc) derivative guests with MOC-16 host were thoroughly studied by NMR spectra, their optical property by UV-Vis, FL spectra and their electrochemical behavior by CV was also studied. Surprisingly, the fluorescence of MOC-16 quenched rapidly when the ferrocene derivative guests were encapsulated by MOC-16 in water. Hence, it was observed that the fluorescence can be recovered simply by extracting guests from the cage cavity with organic solvent.
