In conclusion we have successfully demonstrated that selec-
tivity in supramolecular recognition can be achieved using a
steric block to discriminate against guests that cannot adopt
the ‘‘U’’ shape geometry required for strong binding. Such a
general strategy is likely to be particularly useful in the binding
of larger, typically more challenging substrates.

Features of both host 2 and the guest make this possible.
First, for the host, with ethylene linkers to the thiourea groups,
a reorientation of the H bond donors to face away from the
central cleft is possible and as such a non-linear binding site is
readily created. Second and most importantly, guests such as
azelate are highly flexible and as such can adopt a low energy

less of the central unit. Due to the central group of 2, the rigid
guests, despite their appropriate size, cannot form strong linear
hydrogen bonds with the thiourea groups (Fig. 5).
