Evaporation-driven regularization of crystallographically ordered arrangements of truncated nanoblocks: From 1D chains to 2D rhombic superlattices

Rhombic superlattices of truncated Mn₃O₄ nanoblocks were constructed by evaporation-driven assembly. The tetragonal crystal lattice of Mn₃O₄ in the nanoblocks was clearly shown to be ordered in the superlattices. Tightly packed 2D rhombic superlattices were produced via loosely packed parallel arrays by stacking 1D chains of the nanoblocks elongated in the a direction of the tetragonal lattice by tuning the evaporation rate.
