Liquid crystal (LC) has long been a feature in Materials Science and Nanotechnology, have recently been extended into theappealing domain of complex hybrid materials. The crystalline structural eff ects of alkoxy chain lengths and the mesogenproperties of hydrogen-bonded (n-OBASA) complexes (n = 5,6,7) have been investigated in recent studies. The LC-basedhybrid nanocomposite materials–obtained by the homogeneous dispersion of zinc oxide nanowires (ZnO NWs) as a dopantinto hydrogen-bonded liquid-crystalline compounds—seem to be particularly promising in this article. Optimizing thegeometry of surface stabilizing electro-optic, LC cell reveals the typical intermolecular hydrogen bond (H-bond) formation. Here, we explore molecular-colloidal hybrid composite matrix formed from LCs and dilute dispersions of orientation-orderedZnO NWs, for eventual potential application in smart switchable display devices. In addition, we investigated the structural,dielectric and optical properties of the nanocomposite, and electro-optical studies which were performed by exploiting thepotential during the conditions before the opening of spectrum acquisition. Our novel fi ndings confi rm that the electric fi eldinduces a charge transfer of the LC molecules to the nanomaterial, which acts as a trap for ionic charges. This eff ect maybe utilized to achieve superior switching operation that is electro-optically tunable. Such dynamic novel switching could beharnessed in smart LCD technology and pave the way towards innovative display modulation techniques.
