Tris-(2-aminoethyl)amine-Intercalated Graphene Oxide as an Efficient 2D Material for Cerium-Ion Fluorescent Sensor Applications.

In this work, we report the covalent functionalization of tris(2-aminoethyl)amine (tren) onto the graphene oxide surface by the ring opening of epoxide with primary amine moieties. The effect of intercalation creates the covalent coordinating moieties in between the basal planes of graphene oxide by increasing the interlayer spacing of 1.08 nm from 0.
