with the corresponding poly(amidoamine) dendrimers as a scaffold, followed by removal
of the protecting groups. The present cyclophane tetramer and octamer showed
enhanced guest-binding affinities toward fluorescent guests such as 6-<i>p</i>-toluidinonaphthalene-2-sulfonate and
6-anilinonaphthalene-2-sulfonate, in comparison with those of monocyclic
cyclophane, reflecting multivalency effects in macrocycles.</span>
