In self-assembly systems diffusion of elemental molecules is significantly affected by interactions between solute and solvent molecules. To study the interaction on solute diffusion coefficients, diffusion coefficients of various solutes such as ordinary organic compounds and organometallic complexes having coordination bondings in liquid organic solvent, liquid water, supercritical carbon dioxide and carbon dioxide expanded methanol, a mixture of carbon dioxide and methanol were measured by the transient response techniques, the Taylor dispersion and chromatographic impulse response method. As a result, the values of diffusion coefficients were mainly dominated by the molecular size, and secondarily affected by the interaction. The diffusion coefficients were roughly correlated by the solvent viscosities over the range from supercritical fluid, gas expanded liquid to liquid states.
