Title: Towards Organized Hybrid Nanomaterials at the Air/Water Interface Based on Liquid-Crystal/ZnO Nanocrystals
Abstract: The ability to self-assemble nanosized ligand-stabilized metal oxide or materials offers an intriguing route to engineer with new tailored properties from the disparate We describe a novel one-pot two-step organometallic approach prepare ZnO nanocrystals (NCs) coated with deprotonated 4(dodecyloxy) acid (i.e., an X-type liquid-crystalline ligand) as a model LC (termed ZnO-LC1 NCs). Langmuir and Langmuir-Blodgett films of the hybrids are investigated. The observed behavior of the ZnO NCs the air/water interface is rationalized by invoking a process mediated by the anchored liquid-crystalline The ordered superstructures form according to mechanism based on ZnO-interdigitation process mediatwed by liquid crystals (termed The external and directed force applied upon compression at the interface and the packing of the ligands that stabilize the cores drives the formation of nanorods of ordered internal To study the process in detail, we follow a nontraditional of thin-film investigation. We collect the films from the interface in powder form (ZnO-LC1 LB), resuspend the powder in solvents and utilize otherwise unavailable experimental The structural and physical properties of the resulting were studied by using electron microscopy, atomic force X-ray studies, dynamic light scattering, thermogravimetric analysis, UV/Vis absorption, and photoluminescence spectroscopy.
