eclipsed orientation of the axial ligand for the Py2CD complex and
the staggered orientation for the Im3NHCD complexes. Although
there is no assurance that the Coflex/MM3 calculation provides a
real structure of a supramolecular receptor, it suggests a possibility
that steric hindrance between the axial ligand and the pyrrole
nitrogen affects a ligand–Fe(II) distance to control the dioxygen
affinity.

Conclusions
The present and previous studies on supramolecular Hb/Mb
models make it possible to design a globin model in which the
FeIITPPS moiety shows a desirable dioxygen affinity. We are trying
to synthesise such a supramolecule. “The higher O2 affinity, the
better O2 receptor” is not always right. It is important to prepare
a dioxygen receptor whose O2 affinity is just appropriate for a
purpose. We prepared various O2 receptors having P1/2 values from
1.5 to 176 Torr.
