Twisted organization : Pyrolysis of nanocrystalline cellulose (NCC)/silica composite films leads to mesoporous carbon materials with long‐range chiral organization (see picture). The NCC acts as a template and the resulting mesoporous carbon has a high specific surface area (>1400 m 2 g −1 ) and accurately replicates the left‐handed helical structure of the chiral nematic NCC films.
