Fig. 1: Schematic representation of UV-induced self-adaptive growth of multiscale ordered structures within the film.

a UV-controlled growth of PC particle column structures. b Molecular structure of film constituents and supramolecular interactions between them. c Schematic diagram of the PC particle columns self-adaptive growth mechanism. d 3D fluorescence distribution maps of micro-sized vertical grating (top) and tilted grating (bottom) constructed inside the films. Scale bars: 10 μm. e Complementary PC patterns controlled by different modes of particle column structure within the film and corresponding 3D fluorescence distribution maps. Intermediate scale bar: 1 cm, Left/right scale bars: 5 μm.
