| Outline of Final Research Achievements |
We systematically prepared 48 gold isocyanide complexes with different substituents. Among them, 28 gold complexes show prominent luminescent mechanochromism. Emission colors of these complexes blue, green, yellow, or orange. We also found that one of the complexes show crystal-to-crystal phase transition upon mechanical grinding. This is uncommon type of crystal change profiles of mechanochromism that is crystal-to-amorphous phase transition. Therefore this finding may lead to the construction of rational molecular design principle for the unique mechanochromic materials.
