title: Aromatic core modified decaphyrins with the largest two-photon absorption cross-sections: syntheses and characterization.
abstract: [structure: see text] Core-modified aromatic decaphyrins with 42pi conjugated electrons exhibit the highest two-photon absorption cross-section value (sigma(2) = 108,000 GM) known for any organic molecule, suggesting possible device applications in the field of nonlinear optics.
