Due to their wide range of applications and biological significance, fluorescent sensors have been an active research area in the past few years. In the present review, recent research developments on fluorescent chemosensors that detect metal ions via cation exchange reactions (transmetalation, metal displacement, or metal exchange reactions) of complexes, quantum dots, and metal-organic frameworks are described. These complex-based chemosensors might have a much better selectivity than the corresponding free ligands/receptors because of the shielding function of the filled-in metal ions. Moreover, not only the chemical structure of the ligands/receptors but also the identity of the central metal ions have a tremendous impact on the sensing performances. Therefore, sensing via cation exchange reactions potentially provides a new, simple, and powerful way to design fluorescent chemosensors.

“…To the best of our knowledge, this technology was explored once for the sol–gel preparation of “nanohybrid supercapacitors”, based on centrifugation technology. Ball milling was also scarcely exploited for the covalent immobilization of organic molecules on an inorganic support such as Al 2 O 3 , silica gel, or graphene oxide. , Moreover, high-energy ball-milling process was applied to provide nanocomposite materials with different oxide nanoparticles with a highly homogeneous crystalline structure and morphology such as iron oxide or TiO 2 anatase nanoparticles. − Mechanochemical reactions were recently reported for the preparation of dispersed nanoparticles of oxide materials from molecular or salts precursors. − …”

Hybrid nanoparticles with a large bridging organic group were prepared by mechanochemical-assisted sol−gel reaction. Planetary ball mill (PBM) was used for the first time to access the bis-silylated precursors, containing complex functionalities (such as hydantoins or a symmetrical urea obtained from α-amino esters). The process is based on a sequential reaction pathway involving liquid-assisted grinding (LAG) and 1,1′-carbonyldimidazole (CDI)-mediated one-pot/ two-step reactions. Then hydantoins and the symmetric urea were used for the one-pot preparation of the corresponding bissilylated compounds in a vibrational ball mill (VBM), followed by the mechanochemical sol−gel preparation of biohybrid bridged silsesquioxane nanospheres of uniform size.
