Porphyrin, phthalocyanine, and their relatives

The file Pthalo.pdf has just been made available.  It shows the
formation of the rings which pair to provide the subunits for the
atom-holding assemblies. It shows how the join between rings confers
handedness to the assemblies. It shows how the atom-holding cavity is
hemi-octahedral and that the cavity of one assembly is identical to
that of each of the other assemblies. It shows how one porphyrin can
join to another if they are of opposite hand and inverted relative to
one another. It shows how the paired ring subunits can form chains if
they are of the same hand. The file is one MB in size because the 19
figures show the atoms in epn-detail, the highest possible detail. The
assemblies are shown both with empty cavities and with atom-filled
cavities. The file,  along with Heme.pdf whose material It extends,
can be downloaded from the "Files for sharing" webpage of the website
