Summary: Novel discotic liquid crystalline (DLC) monomers with a mesogenic 2,8,14-triphenylhexabenzo[bc,ef,hi,kl,no,qr]coronene (HBC) core bearing alternating dovetailed alkyl and linear alkyl chains with a diacetylenic unit at different positions along the chain were successfully synthesized in this study. These monomers exhibited a discotic hexagonal columnar mesophase at room temperature. Depending on the location of the diacetylene unit in the linear alkyl chain (closer to or farther away from the HBC core), different aggregation patterns and reactivities toward photo-induced polymerization were observed. Powder X-ray diffraction, differential scanning calorimetry, polarized optical microscopy, UV spectroscopy, and dynamic light scattering were used to characterize these systems.

Summary: The potential application of hexa-peri-hexabenzocoronene (HBC) nanographene as an anode material in Mg and Ca-ion batteries was explored using DFT calculations. The results show that HBC has high ion mobility, great storage capacity, and higher cell voltage, making it a suitable candidate for use in MIBs and CIBs as an anode material.

Summary: The synthesis of two dicyclopentaannelated hexa-peri-hexabenzocoronene (PHBC) regioisomers demonstrates unique electronic structures, with one stable molecule and the other only characterized in situ with high reactivity. These molecules exhibit low energy gaps and significant singlet biradical characters, opening up new avenues for open-shell polycyclic aromatic hydrocarbons (PAHs).

Summary: Spectroscopy was used to study the excited states of chromophore-connected HBC-dppz complexes with rhenium(I) and ruthenium(II). The HBC-substituted dppz ligand and its corresponding complexes were synthesized and characterized. The interplay of their excited states and the perturbation of the HBC were investigated. These studies provide insight into the design of polyaromatic systems and contribute to the knowledge of dppz systems.

Summary: Stiff DNA fragments can self-assemble into various smectic mesophases in concentrated aqueous solutions by selectively screening blunt-end DNA stacking interactions. The strength of attractions can be controlled to stabilize different phases, demonstrating the potential for precise tuning of DNA blunt-ends as monovalent attractive patches in the assembly of nonconventional DNA-based liquid crystal phases.

Summary: This research demonstrates a method for fabricating room-temperature malleable composites using a noncovalent assembly strategy. The composites exhibit excellent toughness and mechanical strength, and can be programmed and self-healed at room temperature using water vapor stimulation. Additionally, the composites also show metallic luster and potential for thermal dissipation.

Summary: The study reveals that self-assembled structures of hexa-tert-butyl-hexa-peri-hexabenzocoronene (HB-HBC) on the Si(111)-Ag surface form a root 21 x root 21 structure, with changes in adsorption sites and molecular orientations near a full monolayer. At submonolayer coverages, the tert-butyl groups of HB-HBC adsorb on both Si and Ag trimers, while at full monolayer coverage, they only adsorb on Si trimers.

Summary: It is experimentally demonstrated that chemical patterns can direct the self-assembly of blue phases (BPs), regardless of the chemistry and complexity of the material. This suggests that a thermodynamics-based continuum description can be applied to a broad range of materials for the self-assembly of BPs.

Summary: In this study, a thin film based on Hexa-peri-hexabenzocoronenene (HBC)-derived discotic liquid crystal (DLC) carrying polymerizable diacetylene (DA) side chains, called HBC-1,2,4-Ph-DA-C12, was used as a hydrogen sulfide (H2S) gas sensor. Both unpolymerized and polymerized DLC thin films exhibited high gas sensing performance. However, the polymerized DLC thin film showed excellent mechanical properties and high environmental tolerance, although slightly poorer gas sensing compared to the unpolymerized film. The DLC film functions as a gas sensor by exploiting the protic acid doping mechanism of H2S, as confirmed by resistivity measurement and UV-visible absorption spectra. The sensors showed good repeatability at 60% and 80% relative humidity (RH) under N2 and air atmospheres, respectively, with 50% accuracy maintained under N2 after 30 days. The thin films demonstrated a linear response to H2S concentrations of 1-10 ppm (maximal R2 = 0.9947) and a lower limit of detection of 1 ppm. These results indicate that DLC-based gas sensors are excellent for detecting H2S gas.

Summary: Self-assembly is a crucial mechanism for designing multifunctional materials, especially in soft hybrid materials where components of different natures interact to form structures with specific functions. A novel magnetic hybrid material was demonstrated, showing the manipulation of molecular tilt through a delicate balance between topologically-assisted colloidal self-assembly of magnetic nanoparticles and anisotropic molecular interactions in a liquid crystal matrix.
