Selective transport of given substrates through artificial membranes can be achieved by incorporation of electrically neutral or charged carriers. Such mediated transport described for alkali and alkaline‐earth metal cations is reported here for the first time for certain anions using cobyrinate‐type ionophores, and it is also conceivable to be realized for nonionic substrates ( e.g. glucose). The fundamental requirements for corresponding co‐transport and counter‐transport membrane systems are set forth in view of a design of novel substrate‐selective sensors for analytical‐chemical applications.
