| Research Abstract |
Even in a simple open system, we can find an emergence of hierarchical orderliness from an nm to mm scale through the interaction between self-assembly and a dissipative structure formation. We have studied the emergence in chemical systems from the viewpoint of thermodynamics and experiments. (1) The relation between thermodynamic quantities and the emergence was studied in a reaction-diffusion model in which the interaction between the system and its environment was included. It was shown that the entropy change (the sum of entropy production and entropy flow across the boundary of the system) calculated by using the newly defined chemical potential was an appropriate quantity for discussing the thermodynamics in an emergent non-equilibrium system. (2) It was designed a model system in which a macroscopic logarithmic spiral (mm) emerges from a dewetting liquid film of C_<60> (nm) in toluene via formation of C_<60> microcrystals (μm). A mathematical model for describing this phenomenon was constructed, and the physical properties of solvents and solutes were extracted.
