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.

在自组装系统中，元素分子的扩散受到溶质和溶剂分子之间相互作用的显着影响。为了研究溶质扩散系数的相互作用，采用瞬态响应技术、泰勒色散和色谱法测定了普通有机化合物和具有配位键的有机金属配合物等各种溶质在液态有机溶剂、液态水、超临界二氧化碳和二氧化碳膨胀甲醇、二氧化碳和甲醇混合物中的扩散系数。 脉冲响应法。因此，扩散系数的值主要受分子尺寸的影响，其次受相互作用的影响。扩散系数与超临界流体、气体膨胀液体到液态范围内的溶剂粘度大致相关。
