“…Through the weak interaction of hydrogen bonds, π–π stacking, and so on, these complexes could be connected into special 1D, 2D, and 3D supramolecular complexes . Over the past few decades, these metal complexes have been attracting widespread concerns on their potential applications in various fields such as magnetism, catalysis, luminescence, and bioactivity . Particularly, transition metal complexes have excellent catalytic properties, especially in catalyzing CC and CN bond forming reactions .…”
