Bottom-Up Construction of POM-Based Macrostructures: Coordination Assembled Paddle-Wheel Macroclusters and Their Vesicle-like Supramolecular Aggregation in Solution

A bottom-up
approach to obtain nanoclusters and large, uniform
vesicle-like structures containing organic functionalized hexamolybdates
in solution state were developed. Hexamolybdate functionalized carboxylic
acid coordinated with two copper ions to form paddle-wheel tetrapolyoxometalate
clusters with the features of macro-ions, which can spontaneously
assemble into large, stable blackberry-type structures in suitable
solvents, completing a hierarchical organization from small POM molecules
to nanoscale complexes and then to supramolecular structures.
