The role of the spacer in discotic polymers

Confined Synthesis of a cis‐Isotactic Ladder Polysilsesquioxane by Using a π‐Stacking and H‐Bonding Superstructure

“…This reference polymer also shows a similar XRD pattern consistent with a lamellar structure (Table 1), which is a common characteristic of discotic side-chain polymers [19,20] as well as semirigid ladder polymers. [2,[5][6][7][8] In other words, such similarity in the XRD patterns also demonstrates that 6 is a linear ordered polymer.…”

Ordered nanostructures at two different length scales mediated by temperature: A triphenylene‐containing mesogen‐jacketed liquid crystalline polymer with a long spacer

“…Generally, Tp DLCs tend to stack on one another to self‐organize into a well‐ordered supramolecular column because of the π–π stacking of the planar aromatic cores and the van der Waals interactions of the peripheral alkyl chains. Many Tp derivatives including Tp‐based molecules, side‐chain LC polymers, and main‐chain LC polymers have been reported to form 2D Φ H phases at ambient temperature. The d ‐spacing of ∼0.44 and ∼0.36 nm for the two halos in the high‐angle region represent the characteristic dimensions of the amorphous packing of the alkyl chains and the π–π stacking in a discotic LC column.…”

Low molecular weight and polymeric triphenylenes as hole transport materials in organic two‐layer LEDs

“…l,lO-Di-[3',6',7',10',1l'-pentabutyloxytriphenylenyl-2-oxyl-decane 3 represents an example of a series of derivatives that will be published elsewhere. Poly(2-[3',6',7',10',ll'-pentabutyloxytriphenylenyl-2-oxy]ethyl) acrylate 4 was prepared according to a known procedure [21] from the corresponding acrylate monomer [22]: 140 mg acrylate monomer (0.2 mmol) was dissolved in 2 mL ethanol and 1 mol-% of AIBN was added. The mixture was degassed by freezing, evacuation, and flushing with argon three times and subsequently heated to 70°C for 15 h with stirring.…”
