Expansion of the Graphdiyne Family: A Triphenylene-Cored Analogue

Graphdiyne (GDY) comprises an important class in functional covalent organic nanosheets based on carbon–carbon bond formation, and recent focus has collected in the expansion of its variations. Here we report on the synthesis of a GDY analogue, TP-GDY, which has triphenylene as the aromatic core. Our liquid/liquid interfacial synthesis for GDY (J. Am. Chem. Soc.2017, 139, 3145) was modified for hexaethynyltriphenylene monomer to afford a TP-GDYfilm with a free-standing morphology, a smooth texture, a domain size of >1 mm, and a thickness of 220 nm. Resultant TP-GDYis characterized by series of microscopies, spectroscopies, and thermogravimetric and gas adsorption analyses.
