The synthesis of zinc phthalocyanine based stopcocks for selective adsorption at the channel entrances of zeolite L is reported. The introduction of either an inert SiMe3 moiety, a imidazolium cation or a reactive NCS group allows attachment to the channel entrances of zeolite L via van der Waals interactions, electrostatic or covalent binding, respectively. Stopcocks that rely on van der Waals driven adsorption require a careful selection of the solvent used for the deposition onto the zeolite surface to avoid a non-specific distribution of the molecules. Regarding the design of photonic antenna systems, a stopcock with a cationic tail was found to be the most convenient, based on the observation that efficient energy transfer from molecules located in the zeolite nanochannels is more readily obtained than in the other cases.
