We found that synthetic parameters such as concentration and metal salt-to-ligand ratio and different coordinative counter anions (Br -, I -, NO3 -, and OAc -), play an important role in shaping the size and morphology of our materials. As a result, a series of different structures resembling rods, sheafs, spherulites, and plates were obtained. We hypothesize that the hyperbranching is caused by an increasing number of defects on the initially fast grown rods. After a certain time, the basal facets become less reactive and instead material is being added to the prism facets. The rate of the secondary nucleation and subsequent crystal growth (= branching) is reflected in the formation of the triangular "branches". These initial branches are fully connected to the surface of the rod. Continuous growth in the lateral direction results in square branches longer than the central slower growing rod. The here reported crystals are the first of such MOF superstructures and the apparent branching mechanism can explain some of the crystal shapes formed with other materials. They are certainly unusual within this class. In spherulites, narrow fibrils are often formed because of competition and geometric constraints. Here, each crystal is competing by growing larger faces, not fading into a collective behavior. Our finding could be extended to other coordination materials so that similar and new branched morphologies can be obtained with unique optical properties. Supporting Information.
