Hi Shivam,
Scripting it in VMD would be my solution, but that is my solution to
most things, so I might be biased. If you have one copy of your
functional group made in Avogadro or Molefacture, you would add it to
your sheet in VMD as many times as needed, merge the functional groups
to your sheet, and then add bonds and guess angles and dihedrals.
Pseudocode for a TCL script would look something like:
#Load your graphene
for { set i 0 } { $i < $numfunctionalgroups } { incr i } {
#Load your functional group
#Place your functional group
}
package require topotools
set newmol [::TopoTools::mergemols [molinfo list]]
#Add in the bonds between functional groups and the main sheet
topo guessangles
topo guessdihedrals
#Write out your new files.
However, before you go filling in the blanks, I'd do a bit of googling
first to see how other folks made graphene oxide in their own studies,
since you aren't the first to look at making graphene oxide, so there
may be tools that exist that I know nothing about.
