he electronic characteristics of a planar covalent organic
framework (COF) on graphene are investigated by means
of dispersion-corrected density functional theory. The
aromatic central molecule of the COF acts as an electron
donor to graphene, while the linker of the COF acts as an
electron acceptor. The concerted interaction between the
filled orbitals of the central molecule and empty orbitals of
the linker promotes the formation of planar COF networks on
graphene. The calculation results are in very good agreement
with experimental findings of an ordered hexagonal and
square COF planar on graphene, which sheds light on the
super molecular assembly mechanism.
