Electronic and photophysical properties of an atomically thin bowl-shaped beryllene encapsulated inside the cavity of [6]cycloparaphenylene (Be_n@[6]CPP)

Abstract

The myriad of applications have triggered the pursuit on exotic metallic nanostructures and among them ultrathin membranes are currently the heart of several investigations since the graphene is ascertained. The...

Host–guest cooperative bridged bicyclopolyynic (BBP) open-molecular cages with optical-switching properties

“…[13][14][15] To date, unique properties are derived from a variety of synthetic allotropes, including nanotubes, fullerenes, and graphene, having sp 2 -hybridized C atoms. [15][16][17][18][19][20][21][22] Although the linear polyynic framework with sphybridized C is synthetically challenging, it was successfully isolated and characterized with the persistent and dedicated efforts of a few research groups. 13,23,24 As terminal alkynes are highly unstable, the synthesis of polyynic structures became feasible by stabilizing with non-reactive end-capping groups.…”
