Morphological transformation. a Transformation relationship and optical memory states for nanobelts, nanospheres, and nanosheets (NS-1). Transformation conditions under ultrasound: A, in H2O; B, in DMF/H2O (v/v = 1/2, water content: 67%); C, in DMF/H2O (v/v = 5/2). State 01 refers to interlayer emission off + intralayer emission on, and State 11 refers to interlayer emission on + intralayer emission on. b Emitting color tone shown by CIE coordinates
