AB  - The guest adsorption phenomena in multicomponent metal-organic frameworks (MOFs) 
      are intricate due to their structural complexities. In this work, we studied two 
      members of the isostructural series of MUF-77 frameworks that consist of long or 
      short alkyl groups. The adsorption of methanol, N,N-dimethylaniline (DMA) and 
      acridine orange (AO) in two structures of MUF-77 has been investigated. (2)H 
      solid-state nuclear magnetic resonance (SSNMR) and two-dimensional (1)H-(13)C NMR 
      spectroscopy were used to probe the dynamics of various compartments of MUF-77. 
      Through the analyses of dynamic behavior by SSNMR and molecular dynamics 
      simulations, we elucidate the spatial distribution of guest molecules are 
      nonuniform around different chemical components, in different pore structures, 
      and across different parts of MOF lattice. In addition, we reveal that the 
      framework flexibility of MUF-77 with short alkyl groups is reduced upon guest 
      adsorption yet the framework flexibility of MUF-77 with long alkyl groups 
      increases upon loading with methanol.
