The 28-hetero-2,7-naphthiporphyrins
reacted with triethylamine
and diethylamine to form nonaromatic intracavity-extended macrocycles
incorporating naphthodihydro-2H-pyran, naphthotetrahydropyridine,
and naphthopyrrolotetrahydro-1H-azepine moieties.
The new macrocycles were characterized in solution by means of NMR
and UV–vis spectroscopy and in the solid state by XRD.
