Influence of functional groups on the self-assembly of liquid crystals

The self-assembly of a pair of low-symmetry tetracarboxylic acid molecules and their co-assembly with bridging molecules at the liquid–solid interface

“…Extensive STM investigations have been conducted at the liquid–solid interface in recent years. 11–19…”

“…Extensive STM investigations have been conducted at the liquid-solid interface in recent years. [11][12][13][14][15][16][17][18][19] Among the intermolecular noncovalent driving forces of molecular self-assembly, hydrogen bonding is the strongest and therefore one of the most important methodologies for preparing supramolecular structures. In addition, the selectivity and directivity of hydrogen bonds are noteworthy aspects concerning molecular self-assembly, and the self-assembly structures driven by the hydrogen bonds are more predictable and controllable.…”

Regulation of the Assembled Structure of a Flexible Porphyrin Derivative Containing Tetra Isophthalic Acids by Coronene or Different Pyridines

“…Supramolecular chemistry, a highly intersecting science, has great influence in the fields of biology, chemistry, materials, and physics. Self-assembly, especially, is one important direction of supramolecular chemistry. − Molecular self-assembly is usually the result of the synergy of multiple interaction forces. While supramolecular self-assembly refers to molecules that form an ordered structure spontaneously through noncovalent bonds as intermolecular forces, and then the assembled molecules are physiosorbed on the surface of the substrate. , Since the stability and efficiency of a device are closely related to the molecular arrangement at the interface, it is meaningful to devise a molecular material with a stable configuration and specific properties with this approach. , “Bottom-up” molecular assembly techniques provide the basis for the production of molecular devices so that the self-assembled molecular networks formed on the two-dimensional (2D) surface with a variety of different functions have always been the focus of people’s attention. − …”

Solvent-Dependent Molecular Isomerization and 2D Self-Assembled Phase Transitions of Benzothiadiazole-Based π-Conjugated Fluorophore

“…In addition, we manage to control the self-assembled nanostructures of the molecules on the two-dimensional surface by adjusting the solution concentration and the type of solvent. This kind of long core liquid crystal molecule are rarely reported in the field of 2D molecular self-assembly relatively. , …”

“…This kind of long core liquid crystal molecule are rarely reported in the field of 2D molecular self-assembly relatively. 30,35 Herein, we describe a systematic STM investigation of FHP-C14 molecule on the graphite surface. This molecule might adopt several types of conformations as a result of free rotation about the bonds between the acetylene and phenyl thiophene.…”
