Nanocubes: “Cubism” on the Nanoscale: From Squaric Acid to Porous Carbon Cubes (Small 21/2016)

Abstract

The development of convenient and efficient template‐free methods for the synthesis of hierarchical porous carbon materials is highly desirable. On page 2906, N. Fechler and co‐workers prepare porous crystalline particles with a 3D cubic morphology by a one‐step, template‐free coordination of zinc ions to squaric acid molecules. Subsequently, these crystalline particles could be transferred into cubic hierarchical carbon to form carbon‐based composites with excellent capacitive performance.
