| Outline of Final Research Achievements |
Several gold-isocyanide complexes with various structures were synthesized and
investigated in detail. The directions of molecule arrangements in the new crystal phases generated by the small mechanical stress were random. The crystal structure and their phase direction of the crystal before the phase change did not influence the direction of the new crystal phase. We also found a new luminescent mechanochromic material with four different colors. We further discover a new gold-isocyanide complex that can undergo single-crystal-to-single-crystal phase change by irradiation of UV light. This complex shows a photosalient property.
