(A) Schematic illustration of single-component DgpC cocrystal microrods fabricated by primary self-assembly and core/shell microrods based on DgpC cocrystal fabricated by horizontal epitaxy process (Adapted with permission from Ref. [135]. Copyright©2021, Wiley-VCH GmbH). (B) Schematic of the specific structures and emission properties of each layer in DgpC-TCNB/DgpC-TFP/DgpC core/double-shell microwires. (C) FM image of DgpC-TCNB/DgpC-TFP/DgpC core/double-shell microwires showing white emission due to the synergistic effect of the multishells. Scale bar is 100 μm (Reproduced from Ref. [135].Copyright©2021, Wiley-VCH GmbH). (D) The process of preparing BTB/BTP core/multi-shell organic microwires by horizontal epitaxial growth method and the specific structure diagram of the core/multi-shell microwires. (E₁), (E₂) FM images of core/triple-shell organic microwires excited with ultraviolet light (E₁) and green light (E₂). The obvious shell structure can be seen in the photo excited by green light. Scale bars are 10 μm (Reproduced from Ref. [123]. Copyright©2021, The Author(s)). (F)–(H) Schematic illustration of the rational design and elaborate synthesis of organic superstructure microwires combining multiblock and multishell structures and the corresponding fluorescence microscopy images. (F₁), (F₂) FM images of different types segmented-core/shell organic superstructure microwires. (G), (H) FM images of different types core/shell-segmented organic superstructure microwires. Scale bars are all 20 μm (Adapted with permission from Ref. [123]. Copyright©2021, The Author(s)).
