“…BCP-templated nanocomposite structures, in which nanoparticles are forced into specific domains, have been reported both in simulations [44] and experiment, [45][46][47] but they have the same limitations as the conventional nanocomposites mentioned in the introduction (mixing, agglomeration and low inorganic volume fractions). An alternative route is to use HNPs where the hairs are BCPs [48,49] or liquid crystal mesogens [50,51] . This design allows for much more controlled structure formation (Fig.…”

Over the past three decades, the combination of inorganic-nanoparticles and organic-polymers has led to a wide variety of advanced materials, including polymer nanocomposites (PNCs). Recently, synthetic innovations for attaching polymers to nanoparticles to create "hairy nanoparticles" (HNPs) has expanded opportunities in this field. In addition to nanoparticle compatibilization for traditional particle-matrix blending, neat-HNPs afford one-component hybrids, both in composition and properties, which avoids issues of mixing that plague traditional PNCs. Continuous improvements in purity, scalability, and theoretical foundations of structure-performance relationships are critical to achieving design control of neat-HNPs necessary for future applications, ranging from optical, energy, and sensor devices to lubricants, green-bodies, and structures.

“…GNPs covered with various calamitic molecules having a terminal thiol group connected linearly or laterally to the molecule, such as cyanobiphenyl thiol, cyclohexylphenoxy thiol and many derivatives of biphenyl thiol, have been reported to exhibit nematic, smectic and columnar phases. [29][30][31][32][33][34][35][36] Similarly, thiol-terminated bent-core ligands have also been used to prepare mesogen-passivated GNPs. 37 A number of physical studies have been performed on these LC-GNP composites.…”

Discotic liquid crystals (DLCs) are nanomaterials with sizes ranging from 2 to 6 nm, and they are emerging as one-dimensional organic semiconducting materials. Recently, hybridization of these materials with various metallic and semiconducting nanoparticles (NPs) to alter and improve their properties has been realized. This article provides an overview of the developments in the field of newly immersed discotic nanoscience, a sub-field of liquid crystal (LC) nanoscience. As this field is also of great interest to readers without an LCs background, a brief introduction of the LC field is given first, with special emphasis on DLCs. This is followed by various DLC-NP hybrid systems. Finally, an outlook into the future of this newly emerging, fascinating and exciting field of discotic nanoscience research is provided.

“…A particularly striking case is that of spherical nanoparticles (NP), typically gold ones, decorated with mesogens attached radially or tangentially with a flexible thiol terminated spacer group to the gold surface [10][11][12][13][14][15], similar in various ways to first generation dendrimers, and forming various liquid crystalline phases.…”
