[Chemical equation presented] Terphenyl derivatives 3 and 4 having OTBS groups have been synthesized via a Suzuki-Miyura coupling reaction. These compounds undergo unprecedented irreversible cyclization to symmetrically/ unsymmetrically substituted triphenylenes while carrying out the deprotection of OTBS groups using tetrabutylammonium fluoride. Terphenyl 3 also serves as a new chemodosimeter for fluoride Ions.

, p. 39 - 45 (2000)
The title compound was found to form an inclusion complex crystal with various kinds of guests. It was also found that crystalline lattice of some inclusion complex is chiral. By an enantioselective inclusion complexation in the chiral lattice, the racemic guest was resolved. The chiral crystalline lattice was studied by X-ray analysis. Solid-state synthesis of the title host compound is also described. Copyright
Self-Organized Frameworks on Textiles (SOFT): Conductive Fabrics for Simultaneous Sensing, Capture, and Filtration of Gases
Smith, Merry K.,Mirica, Katherine A.
, p. 16759 - 16767 (2017)
Wearable electronics have the potential to advance personalized health care, alleviate disability, enhance communication, and improve homeland security. Development of multifunctional electronic textiles (e-textiles) with the capacity to interact with the local environment is a promising strategy for achieving electronic transduction of physical and chemical information. This paper describes a simple and rapid approach for fabricating multifunctional e-textiles by integrating conductive two-dimensional (2D) metal-organic frameworks (MOFs) into fabrics through direct solution-phase self-assembly from simple molecular building blocks. These e-textiles display reliable conductivity, enhanced porosity, flexibility, and stability to washing. The functional utility of these integrated systems is demonstrated in the context of chemiresistive gas sensing, uptake, and filtration. The self-organized frameworks on textiles (SOFT)-devices detect and differentiate important gaseous analytes (NO, H2S, and H2O) at ppm levels and maintain their chemiresistive function in the presence of humidity (5000 ppm, 18% RH). With sub-ppm theoretical limits of detection (LOD for NO = 0.16 ppm and for H2S = 0.23 ppm), these constitute the best textile-supported H2S and NO detectors reported and the best MOF-based chemiresistive sensors for these analytes. In addition to sensing, these devices are capable of capturing and filtering analytes.

2,3,6,7,10,11-Hexahydroxytriphenylene of good quality and purity can be obtained via anodic treatment of catechol ketals and subsequent acidic hydrolysis. The electrolysis is conducted in propylene carbonate circumventing toxic and expensive acetonitrile.

, (2021)
Triphenylene derivatives have been reported as one of the prominent members of discotic liquid crystalline systems. This report gives an account of the mesomorphic behavior of complexes involving triphenylene and double tail surfactants synthesized through the ionic self-assembly route. The lamellar structure of these complexes has been determined using X-ray diffraction, differential scanning calorimetry and polarizing optical microscopy. The amphotropic nature of these complexes has also been studied.

Boroxine and dioxaborole are the first and some of the most studied synthons of covalent organic frameworks (COFs). Despite their wide application in the design of functional COFs over the last 15 years, their synthesis still relies on the original Yaghi's condensation of boronic acids (with itself or with polyfunctional catechols), some of which are difficult to prepare, poorly soluble, or unstable in the presence of water. Here, we propose a new synthetic approach to boroxine COFs (on the basis of the transesterification of pinacol aryl boronates (aryl-Bpins) with methyl boronic acid (MBA) and dioxaborole COFs (through the metathesis of pinacol boronates with MBA-protected catechols). The aryl-Bpin and MBA-protected catechols are easy to purify, highly soluble, and bench-stable. Furthermore, the kinetic analysis of the two model reactions reveals high reversibility (Keq ～1) and facile control over the equilibrium. Unlike the conventional condensation, which forms water as a byproduct, the byproduct of the metathesis (MBA pinacolate) allows for easy kinetic measurements of the COF formation by conventional 1H NMR. We show the generality of this approach by the synthesis of seven known boroxine/dioxaborole COFs whose crystallinity is better or equal to those reported by conventional condensation. We also apply metathesis polymerization to obtain two new COFs, Py4THB and B2HHTP, whose synthesis was previously precluded by the insolubility and hydrolytic instability, respectively, of the boronic acid precursors.

Paragraph 0396; 0397; 0398, (2019/02/13)
An organic compound, a three-dimensional organic structure formed by using the organic compound, a separation sieve and an optical layer having the organic structure, and an optical device having the optical layer as an optical amplification layer are provided. The organic structure includes a plurality of organic molecules self-assembled by non-covalent bonding. Each of the unit organic molecules has an aromatic ring, a first pair of substituents being connected to immediately adjacent positions of substitutable positions of the aromatic ring, and a second pair of substituents being connected to immediately adjacent positions of remaining substitutable positions of the aromatic ring. The unit organic molecules are self-assembled by van der Waals interaction, London dispersion interaction or hydrogen bonding between the first and the second pairs of the substituents and by pi-pi interactions between the aromatic rings.
