Characterizations of CHICZ single crystals. a Molecular structure of CHICZ. b SEM image of CHICZ crystal ribbons. Scale bar: 20 μm. c and d Molecular packing in CHICZ single crystal seen from different directions. e TEM image and its corresponding SAED pattern of an individual CHICZ single crystal in which CHICZ molecules are packing along the b axis with π−π stacking. Scale bar: 1 μm. f and g Fluorescence microcopy images of CHICZ ribbons showing less loss coefficients in long distance and good flexibility. Scale bar: 50 μm
