advances in the programmable synthesis of nanostructured
materials and additive three-dimensional (3D) manufacturing have created
a rich and exciting opportunity space to fabricate novel materials
and devices. In particular, creating complex hierarchical device geometries
from mesoporous materials presents several scientifically interesting
and technologically relevant challenges. Here, we show how digital
light processing of photoresponsive building block defined by an oxozirconium
methacrylate cluster with 12 methacrylic acid ligands can be used
to enable the creation of complex superstructures characterized by
multilevel porous networks. Inspired by similarly complex 3D hierarchical
mesoporous structures ubiquitous in nature, we demonstrated the fabrication
of a 3D leaf as a proof of concept. This work demonstrates how exciting
opportunity space emerging at the intersection of inorganic building
blocks, mesoporous materials, and 3D digital light processing opens
new pathways to create functional hierarchical superstructures and
devices with complex geometries.
