A 3D Calcium Spirobifluorene Metal–Organic Framework: Single-Crystal-to-Single-Crystal Transformation and Toluene Detection by a Quartz Crystal Microbalance Sensor

A new 3D metal–organic framework Ca-SBF based on a zigzag-shaped tetranuclear calcium oxocluster and 9,9′-spirobi­[9H-fluorene]-2,2′,7,7′-tetracarboxylic acid was obtained and exhibited flu topology. Ca-SBF underwent a single-crystal-to-single-crystal transformation to form Ca-SBF-1 with a slight st...

Summary:A new 3D metal–organic framework Ca-SBF based on a zigzag-shaped tetranuclear calcium oxocluster and 9,9′-spirobi­[9H-fluorene]-2,2′,7,7′-tetracarboxylic acid was obtained and exhibited flu topology. Ca-SBF underwent a single-crystal-to-single-crystal transformation to form Ca-SBF-1 with a slight structure shrinkage. Activated Ca-SBF showed permanent porosity and CO2 adsorption properties. A Ca-SBF-modified quartz crystal microbalance sensor demonstrated selective response to toluene vapor.
