Semiconductive Nature of Lead-Based Metal–Organic Frameworks with Three-Dimensionally Extended Sulfur Secondary Building Units

Recently, metal–organic frameworks (MOFs) composed
of sulfur
secondary building units (sulfur-SBUs) have attracted significant
attention as unique electronic materials with high conductivities
and photo- and electrocatalytic properties. Herein we report the crystal
structure of KGF-1, an example of a Pb-MOF composed of three-dimensionally
extended sulfur-SBUs that displays molecular sieving behavior, visible-light
absorption, and a semiconductor band structure and is a hydrogen-evolution
photocatalyst.
