Abstract

Graphdiyne analogs, linked carbon monolayers with acetylenic scaffoldings, are fabricated by adopting low-temperature chemical vapor deposition which provides a route for the synthesis of two-dimensional carbon materials via molecular building blocks. The electrical conductivity of the as-grown films can reach up to 6.72 S cm^-1 . Moreover, the films show potential as promising substrates for fluorescence suppressing and Raman advancement.

Keywords: Raman enhancement; chemical vapor deposition; homocoupling reaction; linked carbon monolayers; on-surface covalent synthesis.
