A novel morphology of TPBD crystals consisting of a three‐dimensional interlaced network was obtained by casting the self‐seeded 0.1% benzene solution onto carbon‐coated mica. Both the transmission electron microscopy (TEM) and electron diffraction (ED) analyses showed that the network was composed of well‐developed lamellae. It is imagined this interesting morphology is the result of asymmetrical growth of the original TPBD lamellae on the amorphous interface, and that their preferred orientation changed when they encountered each other.
