Bottom-Up Porous Graphene Synthesis and its Applications.

Incorporation of regular order pores/holes/defects into semimetalic graphene sheets can tune the band gap up to 1 eV or more introducing semiconducting property and therefore exhibiting promising applications for organic electronics such as field-effect transistors (FETs), molecular sieve membranes, gas sensing, catalysis devices, etc. In this mini review, we focused on bottom-up approaches to introduce periodic homogeneous pores into graphene and nanographene and graphene nanoribbons along with their characteristics and potential applications in various fields.
