Can't find a single page about fluorographane

Not a typo. Fluorographene is the sp² form (Nair et al. 2010). Fluorographane uses the -ane suffix to denote full sp³ saturation — same convention as graphene → graphane. The sp³ hybridization is what creates the bistable C-F orientation that stores the bit.
