1. A method for depositing multilayers of different semiconducting organic polymers comprising depositing a layer of semiconducting organic polymer polymerised by exposing an oxidising agent to a vapour containing the monomer to be polymerised and depositing at least one other layer of a different semiconducting organic polymer polymerised electrochemically and wherein the multilayers of semiconducting organic polymer are deposited on a device that includes a substrate surface and is used as a gas sensor and wherein said device contains at least one pair of electrodes and said multilayers are deposited onto and between said pair of electrodes to effect a semiconducting electrical connection.
