Outline of Final Research Achievements

We have successfully fabricated well-defined diacetylene (DA) nanocrystals, and clarified size-dependence of structural phase transition in solid-state polymerization of the DA nanocrystals. In particular, solid-state polymerization of DA nanofibers quantitatively proceeded due to suitable stress-strain behavior, compared with both nanocrystal and bulk crystal. In addition, we found that third-order nonlinear optical susceptibility of polydiacetylene nanofiber was superior to that of bulk crystal.
