title: Strong two-photon and three-photon absorptions in the antiparallel dimer of a porphyrin-phthalocyanine tandem.
abstract: Imidazolyl-appended phthalocyaninatozinc(II) containing an ethynylporphyrin linkage was stacked by complementary coordination into an antiparallel dimer that displayed strong nonlinear optical properties involving two-photon and three-photon absorptions.
