About the cover

September 2014 Volume 6 No 9

Making 2D materials from the bottom up in a precise fashion poses significant challenges in terms of both synthesis and characterization. Now, two research groups — led by Benjamin T. King and Dieter Schlüter — have shown that 2D polymers can be formed in a single-crystal-to-single-crystal process, and each step along the way has been characterized by X-ray crystallography. On the cover is a polarized optical microscopy image of a 2D polymer single crystal made by Schlüter and co-workers, showing exfoliation of the layered structure.
