title: Two-photon absorption in porphycenic macrocycles: the effect of tuning the core aromatic electronic structure.
abstract: Changing the core heteroatoms in porphycenic macrocycles can have a dramatic effect on the two-photon absorption properties via tuning of resonance enhancement between Q-band and Soret-band states.
