Fig. 1: Concept and preparation of magnetic hybrid flexible crystals.
From: Remote and precise control over morphology and motion of organic crystals by using magnetic field
a Chemical structures of elastic crystals 1–6. b Reversible bending and unbending of acicular crystals 1–6. The process was observed by using the emission of these crystals under 365 nm UV light for better contrast with the dark background. c A procedure for charge-driven assembly of magnetic nanoparticles (MNPs) onto flexible organic crystals (Red vertical lines represent flexible organic crystals). d Preparation of the hybrid crystals MNP//1–6. e Schematic diagram showing the mechanism of bending of MNP//1–6 in a magnetic field. f Photograph of MNP//5 in daylight. g False-colored scanning electron micrographs showing the cross-section of the crystal hybrids. The crystal is shown in orange color, the polymer coating is in blue, and the Fe3O4 MNPs are in light grey color. h Schematic cross-section of the magnetic hybrid flexible crystals MNP//1–6.
