Formation of large BPI single crystals by self-reassembly and pseudomorphism. Formation process: microscopic images of M1 (a), upon cooling to BPII from ISO (b), upon holding for 36 h in BPII (c), upon cooling to BPI (d), upon holding for 24 h in BPI (scale bars, 300 μm). Optical characterization of BPI monocrystal and polycrystal: e reflection spectra and f microscope images (scale bar, 100 μm). See “Methods” for experimental details
