We report the first method to introduce differential functionalities in the interior pore walls and exterior surface of highly stable thermally hydrocarbonised porous silicon (THCpSi) films. The approach exploits the hydrophobicity of the hydrosilylated THCpSi to, first, selectively functionalise the external surface, and subsequently derivatise the hydrophobic internal pore walls.
