(3) Advanced construction of meso- and macroscopic cooperative photoresponsive
molecular assemblies and elucidation of their mechanisms.
This book compiles the accomplishments of this research project conducted with
these subjects. In Part I, we introduce the research results of the first subject directly
relating to the three general restrictions. By developing and applying multiple and
multiphoton excitations, nano-environments, new materials and theoretical methods, we could find new phenomena beyond the three restrictions and elucidated
their mechanisms, which can lead to the realization of photosynergetic responsive
materials. In addition, the developments of new materials, experimental apparatuses
and theoretical methods in the study have ensured further progress of the research
field on the photosynergetics.
Part II bundles research outcomes on the second subject aiming to explore
photoresponsive systems where the photoreaction in a molecular level is integrated
and amplified. By designing and synthesizing molecules and assemblies, reaction
chains and molecular networks overcoming the loss of the photon energy were
achieved by the amplification. Moreover, many examples were realized for cooperative photoresponses of molecular aggregates arising from the integration of
molecular photoreactions. From these results, we could obtain the principles for the
realization of responses through the multiple photons and multiple excited molecules, which can guide future research.
Part III compiles the photoresponse of materials in rather large scale, where the
individual reaction of molecules in the excited state is accumulated in the material,
leading to the hierarchical photoresponse of meso- and macroscopic materials.
Researchers in various fields of materials chemistry such as molecular synthesis,
designing of molecular crystals, time- and space-resolved detection of reaction
dynamics developed photoresponsive meso- and macroscopic systems and elucidated their mechanisms. These new phenomena, materials, mechanisms and
experimental methods can lead to the further advancement of photosynergetics.
We hope that the achievement of the project is a significant landmark and
principles in the stream of studies on the photochemistry of molecules and
materials.
The editors express their sincere appreciation to outstanding contributors and to
the Ministry of Education, Culture, Sports, Science and Technology, Japan, for
their support of the project.
