My presentation title was “Molecular assemble structure and optical properties of propeller isomer of trialylmethane dye type zinc complexes”.

TAM complexes crystalized in either needle or octahedral shape, or both. Crystal structure analysis revealed that a needle crystal was composed of molecular columns, in which P- and M-forms of propeller-shaped complexes were alternatively stacked. In contrast, octahedral crystals had more complicated, enantiomeric cubic system. The crystals with columnar packing structure exhibited linearly-polarized emission. The crystals with cubic system did not show recognizable dichroism neither in absorption nor emission. The difference in photophysical properties was interpreted from the spatial arrangement of TAM dye molecules in the crystals.

I’m glad to win this prize. I’ll work hard more.
