We present a novel soft templating approach (STA) for the elaboration of porous silicon carbide (SiC) in oxygen- and moisture-free atmospheres. In this method, the molecular precursor, 1,3,5-trisilacyclohexane (TSCH) which is in a liquid state at room temperature, is templated by a solid network of semi-fluorinated alkanes (SFA) that self-assele directly in the former liquid.
