Bowl liquid crystal based on cyclotriveratrylene derivatives with multiple triphenylene units: The influences of the numbers of triphenylene units on mesomorphic behaviors

The steric hindrance effect of bulky groups on the formation of columnar superlattices and optoelectronic properties of triphenylene-based discotic liquid crystals

“…Multiplicities of the peaks were denoted as s = singlet, d = doublet, t = triplet, and m = multiplet. 13 C-NMR spectra were recorded in CDCl 3 on a Bruker 700 M NMR spectrometer. The high resolution mass spectrum was recorded on a Bruker Apex IV FTMS mass spectrometer.…”

“…S1-S12, ESI †), 1 H-NMR spectroscopy (Fig. S13-S24, ESI †), 13 C-NMR spectroscopy (Fig. S25-S36, ESI †), and MS (Fig.…”

“…Most previous studies on triphenylene were symmetrical hexasubstituted or asymmetrical mono-, di-and tri-substituted compounds. [9][10][11][12][13][14] For triphenylene ethers, which tend to become polycrystalline at room temperature, the columnar phase is stable only at a higher temperature. [15][16][17][18] A factor hindering practical applications of these discotic liquid crystals was the absence of photoconduction below the crystallization temperature owing to the trapping of charge carriers at structural defects associated with grain boundaries in polycrystalline materials.…”

Cyclotriguaiacyclene-functionalized trans-cinnamic acid with alkyl arms: an efficient supramolecular system for solar cell and liquid crystalline applications

“…28 Yang et al synthesized CTV based triazole linked triphenylene units and investigated their liquid crystalline behaviour. 29 Further, the demethylation of CTV was carried out using different reagents and reactions conditions to form a cyclotriguaiacyclene (CTG) core having three hydroxy groups. 30 The hydroxyl groups of the CTG core can be easily substituted by various moieties for use in host–guest chemistry, self-assembly, sensing, and biomedical application, and in the formation of organic and metal-linked organic ligands (Fig.…”

Controlled Access to C1‐Symmetrical Cyclotriveratrylenes (CTVs) by Using a Sequential Barluenga Boronic Coupling (BBC) Approach

“…C 3 -Symmetrical CTVs have found a wide variety of uses as ion or organic molecule sensors [2,3] building blocks for liquid crystals [3] or purification devices. [4][5][6] CTVs are also known to be precursors in supramolecular assemblies such as capsules, [7][8][9] cryptophanes [10][11][12][13][14][15][16][17][18] and hemicryptophanes.…”
