Graphene is a carbon allotrope.
A CurlySMILES notation for graphene
is composed from the SMILES notation of a carbon atom and a
shape and state annotation:
|
[C]{sdall=graphene}
|
graphene
|
|
Instead of the SSAM sd, other
annotation markers like cr or
tf can be used, depending on focus
and context.
Stoichimetric graphene derivates are encoded by applying the
SFN
format to specify composition and appending an annotation to
supply a common name. Examples are the fully hydrogenated graphene,
graphane [1], and the fully
fluorinated graphene, fluorographene [2]:
|
{*CH}{sdchn=graphane}
|
{*CF}{sdchn=fluorographene}
|
graphane
|
fluorographene
