The highest sheet symmetry form of graphyne, with one triple bond between each neighboring hexagon in graphene, irreversibly transforms exothermically at ambient pressure and low temperatures into a nongraphitic, planar-sheet, zero-bandgap phase consisting intrasheet-bonded sp2 carbons. synthesis this carbon is demonstrated, other phases are described for possible future from graphyne without breaking bonds. While measurements theory indicate that the reacting becomes nonplanar because...
We have successfully achieved selective and efficient functionalization of sheet edges in microcrystalline multilayer γ-graphyne through two methods: cross-coupling with residual bromide edge groups copper-catalyzed azide-alkyne cycloaddition (CuAAC) terminal alkyne groups. This modification significantly enhances the ease mechanical exfoliation dispersibility sheets γ-graphyne. Specifically, C
We have successfully achieved selective and efficient functionalization of sheet edges in microcrystalline multilayer γ-graphyne through two methods: cross-coupling with residual bromide edge groups, copper-catalyzed azide-alkyne cycloaddition (CuAAC) terminal alkyne groups. This modification significantly enhances the ease mechanical exfoliation dispersibility sheets γ-graphyne. Specifically, C18-grafted forms stable dispersions compatible organic solvents, allowing for imaging atomically...
A recent article by Ryu, Lee and coworkers claims synthesis of "holey graphyne," a strained sp2/sp1 carbon lattice featuring repeating dibenzo-1,5-cyclooctadiene-3,7-diyne motif. Here, we describe the replication key experiments from this Article. We did not observe formation graphyne" under reported conditions. Furthermore, show that claimed copper-mediated cross-coupling chemistry fails even for undemanding model substrates.
A key step of inexpensive and scalable perovskite thin-film formation is defect-free fabrication through low-cost facile post-treatment processes. Methods using high annealing temperatures are not favorable for the scale-up solution-processed solar cells, particularly on plastic/flexible substrates. This contribution analyzes effect ultrasonic vibrations, a recently developed process, quality. Ultrasonic vibrations were applied to as-spun CH3NH3PbI3 thin films prepared with various solvents...
