Unique 2D Face Topologies in Naphthyl‐Appended Naphtho[k]fluoranthene‐Based 3D Crystals for Optical Waveguide (Advanced Optical Materials 13/2023)

In article number 2201810, Shotaro Hayashi and colleagues synthesize a naphtho[k]fluoranthene that exhibits efficient fluorescence in solution and in the solid state is successfully established. It selectively gives two crystal topologies derived from direction-specific crystal growth. There are different optical-loss coefficients along the various directions on each face.
