Stopcock fluorophores at the ends of zeolite L channels can trap electronic excitation energy from pyronine+ molecules inside the crystal (see scheme, top). The reverse process, that is, the injection of electronic excitation energy through such stopcocks (bottom), was achieved with oxonine+ molecules inside the zeolite channels.
