A well-defined crystalline cyano-functionalized graphdiyne (CN-GDY) is synthesized at a liquid/liquid interface through alkyne-alkyne coupling reactions. The configurations and nanostructures of CN-GDY were well characterized by TEM, SEM, AFM, XPS, and Raman spectroscopy. HR-TEM and selected area electron diffraction (SAED) in combination with structure simulation firmly revealed a 9-fold stacking mode for CN-GDY.

A new trefoil-shaped molecular architecture consisting of three conjugated macrocycles was synthesized through an unprecedented 3-fold copper catalyzed [4 + 2] benzannulation. DFT calculations indicate that the most stable conformation of this trefoil macrocycle is D3-symmetric. In agreement with the calculated results, the trefoil macrocycle in single crystals exists as a pair of enantiomers with D3-symmetry and exhibits interesting honeycomb-like supramolecular structures.

Paragraph 0395; 0396, (2017/07/26)
Described herein are molecules for use in organic light emitting diodes. Example molecules comprise at least one acceptor moiety A, at least one donor moiety D, and optionally one or more bridge moieties B. Each moiety A is covalently attached to either the moiety B or the moiety D, each moiety D is covalently attached to either the moiety B or the moiety A, and each moiety B is covalently attached to at least one moiety A and at least one moiety D. Values and preferred values of moieties A, D, and B are defined herein.

, p. 643 - 649,7 (2020/08/31)
An efficient synthetic route starting from 1,3,5-trimethylbenzene is described for binary 1,3,5- triazido-2,4,6-tricyanobenzene. Besides 1,3,5-triazido-2,4,6-tricyanobenzene, all intermediates have been isolated and fully characterized.
En route to archimedene: Total synthesis of C3h-symmetric [7]phenylene
Bruns, Dirk,Miura, Hirokazu,Vollhardt, K. Peter C.,Stanger, Amnon
, p. 549 - 552 (2007/10/03)
(Matrix presented) The total synthesis of C3h-symmetric [7]phenylene has been accomplished by triple cobalt-catalyzed cycloisomerization of an appropriate nonayne. Its spectral data are in accord with the expectations for a triply angularly fus
1,3,5 / 2,4,6-Differentiated hexaalkynylbenzenes: Absorption and fluorescence properties of a D(3h)-symmetric donor-substituted system
Anthony, John E.,Khan, Saeed I.,Rubin, Yves
, p. 3499 - 3502 (2007/10/03)
The synthesis of 1,3,5 / 2,4,6 differentially functionalized hexaethynylbenzene derivatives is described. Interesting solvatochromic behavior was observed for 9b in the absorption and emission spectre. A twisted intramolecular charge transfer (TICT) state in polar solvents appears to be involved.
