Construction of Imine-Linked Nanoparticle Organic Networks for Field Effect Transistors: Wet Chemical versus Mechanochemical Approach

摘要: Metal nanoparticles (MNPs) in heterogeneous form have shown impressive potential for a range of applications in optoelectronics, heterogeneous catalysis, and sensing. Various strategies with varying degrees of success have been adopted over the years for the heterogenization of MNPs, including anchoring and/or encapsulation of MNPs in polymers, zeolites, silica, etc. However, these strategies suffer from unavoidable drawbacks, such as leaching and agglomeration-induced deactivation. In this work, we developed a new approach to heterogenize MNPs as networks [nanoparticle organic networks (NONs)] by reacting amine-functionalized MNPs (as nodes) with dialdehydic linkers (as organic struts) at room temperature. Importantly, a green and sustainable mechanochemical synthetic strategy was conceptualized and employed to overcome the limitations of the wet chemical approach to NON synthesis …
