Dimensionally stable, optically clear, highly porous (approximately 65% of the apparent volume), and high surface area (up to 1400 m(2)/g) silica monoliths were fabricated as thick disks (0.5 cm) by templating the isotropic liquid crystalline L(3) phase with silica through the hydrolysis and condensation of a silicon alkoxide and then removing the organic constituents by supercritical ethanol e...
The synthesis of metal frameworks perforated with nanotunnels is a challenge because metals have high surface energies that favor low surface area structures; traditional liquid-crystal templating techniques cannot achieve the synthetic control required. We report a synthetic strategy to fabricate metal nanomaterials with highly ordered, tunable mesostructures in confined systems based on a new...
Examples of chemical systems capable of templating and catalysing their own synthesis—self-replicating systems— have begun to appear in the chemical literature over the last 15 years. For the biologist, these systems represent a link with the origin of life—their study can shed light on prebiotic chemical evolution. However, for the synthetic chemist, they represent the ultimate synthetic machi...
An unprecedented example of concomitant harmonisation of hydrogen bonding and metal-templating to direct a topochemical [2+2] cycloaddition with quantitative yield is reported.
Abstract Computational modeling of organic interface formation on semiconductors poses a challenge to density functional theory‐based description due structural and chemical complexity. A hierarchical approach is presented, where parts the are successively removed in order increase computational efficiency while maintaining necessary accuracy. First, benchmark performed probe validity this for ...
Mn-based oxides have sparked extensive scientific interest for aqueous Zn-ion batteries due to the rich abundance, plentiful oxidation states, and high output voltage. However, further development of is severely hindered by rapid capacity decay during cycling. Herein, a two-step metal–organic framework (MOF)-engaged templating strategy has been developed rationally synthesize heterostructured M...
