Oxidative intercalation of two selected PAN- and pitch-based carbon fibers by bis(fluorosulfuryl)peroxide, S 2 O 6 F 2 , results in materials with enhanced electrical conductivities. The nature and the extent of intercalation show some differences in

The reaction of graphite fluorosulfate with an excess of arsenic(V) fluoride produces the new intercalation compound C 14 + [AsF 5 (SO 3 F)] − . Identification as a first stage compound rests on the observed interlayer separation of 7.92 A and the

The action of bromine(1)fluorosulfate on graphite has led to the synthesis of several novel intercalation compounds. The intercalation of bromine(1)fluorosulfate at room temperature results in a first stage compound, C12BrSO3F, while at higher temper

Graphite fluorosulfates, C n SO 3 F, with n = 7 for stage-one materials, are ideally suited for 19 F n.m.r. studies due to the unambiguous identity of the intercalate and its axially symmetric nature. The intensity of the signal shows a clear depende

The composition of stage 1 graphite fluorosulfate is unambiguously established as C 7 SO 3 F by complete microanalysis. A structural model is proposed involving charge compensating backdonation from S0 3 F - to graphite consistent with NMR, ESR and R
