title: Helicity induction and two-photon absorbance enhancement in zinc(II) meso-meso linked porphyrin oligomers via intermolecular hydrogen bonding interactions.
abstract: Helicity has been induced in meso-meso linked oligomers by hydrogen bonding host-guest interactions with cyclic urea. Helical porphyrin arrays thus formed exhibit chirality amplification and enhanced two-photon absorption properties.
