“…Polyoxometalates (POMs) have attracted special attention in the area of self-assembly as a class of nanobuilding blocks due to their unique structural frameworks, defined sizes, and outstanding intrinsic features . Over the past decade, POM-based chemistry has boomed; an ensemble of new POM clusters with various sizes, structures, complexity, and intrinsic characteristics has been synthesized, , and their self-assembly into thin films, − tubes, , wires, fibers, honeycomb architectures, − vesicles, , etc.…”
