The crystal structures of a thiophene-based terpyridine ligand and its four zinc halide complexes had been discussed. The open-aperture Z-scan results showed that LZnBr2 exhibits the best two-photon absorption property, which is greatly superior to that of the free ligand L.

We report on two-photon absorption and two-photon excited fluorescence of a selected group of new derivatives of cyclohexanone and piperidone with regard to their molecular structure. The molecular cross-section of the two-photon absorption of these compounds, as high as 3000 × 10-50 cm4 s/photon at nanosecond pumping, makes then promising nonlinear materials for optical limiting in the near-infrared region. They also exhibit an intense two-photon exciting fluorescence. Similar compounds have previously demonstrated strong anticancer effect. Both features combined in a single compound thus open the way for more efficient treatment of cancer, when biochemical destruction of malignant cells is accompanied by their two-photon fluorescent imaging.
