摘要
In this study,we present a novel multicomponent self-assembly approach that offers good potential for crafting heterometallic complexes with exceptional constitutional control.This method generates metal ions from a sacrificial anode by using an electric field,which then coordinates with a metal complex precursor.As a proof-of-concept demonstration,we successfully synthesized single crystals of a heterometallic platinum(Ⅱ)-copper(Ⅰ)(Pt[Ⅱ]-Cu[Ⅰ])complex at an exceptionally rapid rate within 30 s by applying a voltage to an acetonitrile solution of[Pt(ppy)(CN)_(2)]^(−)Bu_(4)N^(+),using copper foil as the anode.Intriguingly,by finely adjusting the intensity and duration of the electric field,we achieved a variety of supramolecular structures,spanning from spherical to rod-like and even flower-like morphologies.Additionally,we found that the photoluminescence property of the resultant crystal can be reversibly shifted among green,orange,and cyan by merely altering the solvent environment.Finally,the crafted heterometallic Pt(Ⅱ)-Cu(Ⅰ)complex has shown great promise in advanced anti-counterfeiting applications.
