%X Two new, fused core-modified expanded
porphyrins, sapphyrins 3 and 4, were synthesized
by a simple acid-catalyzed
condensation of electron-rich and rigid precursor, dithienothiophene
(DTT) diol, and core-modified tripyrrane. These sapphyrins exhibit
structural diversity depending upon the heteroatom present in the
macrocyclic framework, where the thiophene ring is inverted in 3, while the selenophene ring in 4 exists in
normal and inverted form in the free base and addition of two protons
shifts the equilibrium to inverted form.
