Abstract

Liquid N,N,N',N'-tetramethyl-ethane-1,2-diamine (tmeda) was intercalated into preprepared C(6)Li or C(12)Li. X-ray diffraction from the ternary compound indicates an identity period of 11.5 Å. The (13)C NMR line shifts show that tmeda molecules form a screen between the graphene planes and the lithium ions. Small-angle X-ray scattering showed that no higher structural ordering was present but revealed a progressive roughening of the surfaces with successive intercalation of lithium and amine into the graphite galleries.
