Mesoporous Organic/Inorganic Hybrid Materials with Frank-Kasper Phases Templated by an Unusual Linear Symmetry Diblock Copolymer

Front Cover: In article number 2100302 by Shiao-Wei Kuo and co-workers, an unusual linear symmetric PEO-b-PCL diblock copolymer as a template within phenolic/DDSQ hybrids is used to synthesize mesoporous materials having Frank–Kasper phases including σ, A15, H, and Z phases. These Frank-Kasper structures are the first to have been prepared using a block copolymer and the first to exist in mesoporous materials.
