Significance Confinement of molecules in nanoscale pores is important both science and technology. This paper reports a systematic analysis the structural, thermodynamic, dynamic behavior on confinement rigid organic molecule series silica frameworks with different pore sizes (0.8 to 20.0 nm). The comprehensive data set enables strength guest–host interactions be calculated; structure, phase, dynamics confined guests various diameters analyzed; types inclusion described. evolution from single-molecule multimolecule adsorption/confinement nanocrystal documented. provides conceptual model linking length scales.
