Core-modified aromatic decaphyrins with 42π conjugated electrons exhibit the highest two-photon absorption cross-section value (σ2 = 108 000 GM) known for any organic molecule, suggesting possible device applications in ...

Acid-catalyzed condensation of furan and pentafluorobenzaldehyde yielded conjugated macrocycles with six and eight furan rings. They represent systems similar to annulenes with 30 d and 40 d electrons. From their structural ...
