Self-assembly of a giant heterometallic polyoxovanadate with catalytic activity for epoxidation of alkenes
The self-assembly of giant polyoxovanadates (POVs) is highly attractive yet extremely challenging, hampered by protonation complexity and structural instability. Here, we obtain the largest POV cluster 1 via self-assembly in aqueous solution, in which tartaric acid serves as a structure-directing agent via synergis...
