Scope of the session

There are increasing reports in solid-state metal complexes which respond to mild stimuli such as heat, light, mechanical force, and vapor to show remarkable color and luminescence changes. The phenomena are well known as thermochromism, photochromism, mechanochromism, and vapochromism, respectively. However, the design of chromic complexes exhibiting intended phenomena is still a challenging theme, and the mechanistic and dynamic investigations based on the structural, spectroscopic, and theoretical studies should be very important. Such chromic phenomena based on the phase-transitions have been subjects of interests not only in coordination chemistry but also in analytical, organic, physical, and biological chemistry.
This symposium will focus on the new aspects of stimulus-responsive metal complexes with photofunctionalities. The targeted systems are highly-ordered assembling complexes although they can easily change the phases by outer stimuli. The new systems which exhibit changes in other physical properties correlating with color changes would be expected. The new approaches such as ultra-fast and/or ultra-fine structure analysis and spectroscopy would be also expected to understand the phenomena. Theoretical approaches should be one of powerful tools now. Through the widely-covered topics concerning photofunctional complex systems, this session will provide a broad overview of key developments in this field including new methodology for the synthesis, analysis and application of stimulus-responsive metal complexes.
