Mechanisms and Intermediates in the True Liquid Crystal
Templating Synthesis of Mesoporous Silica Materials
Posted on 2021-03-16 - 18:19
Mesoporous silica
materials (MSMs) produced by true liquid crystal
templating (TLCT) are often considered as direct inverted replicas
of the initial lyotropic liquid crystal (LLC) phase. However, the
predictive design of tailor-made MSMs requires the full knowledge
of the TLCT process, which is still incomplete. Here, we tackle this
issue by monitoring the structural evolution during the templating
process by small-angle X-ray scattering, showing that after the addition
of the silica source the reaction mixture is first isotropic and then
an intermediary liquid crystal phase appears, which is the key to
the success of the templating process, namely the formation of ordered
MSMs. We analyze the structure and the formation dynamics of this
intermediary phase and present a simple theoretical model, which allows
us to connect the structural parameters of the initial LLC and the
MSM. These results provide an enhanced understanding of the TLCT process
and are an important step toward the predictable synthesis of new
MSMs in the future.
