The intercalation of polypyrrole (ppy) into hexagonal mesostructured carbon at 6.80–12.6 wt.‐% levels results in substantial shrinkage of the framework structure (Δ d 100 = 0.8–1.0 nm) and the pore size (from 3.7 nm initially to 2.9–2.5 nm upon ppy binding). The surface areas (718–960 m 2 g –1 ) and electrical conductivities (0.1–1.0 S cm –1 ) for compressed powders, however, are largely retained over a wide temperature range, providing potential applications in sensing.
