In situ 1H pulsed field gradient (PFG) NMR was used to investigate the mol. diffusion of n-butane in the pores of the flexible metal-organic framework DUT-49(Cu) at 298 K at different pore loadings, including pressure ranges below and above the neg. gas adsorption (NGA) transition caused by structural contraction of the material. Supported by mol. dynamics simulations, the investigation provided crucial insight into confined diffusion within a highly flexible pore environment. The self-diffusion coefficients were derived from the experiment and compared with simulations, capturing the diffusion during n-butane adsorption and desorption. This complementary approach has yielded exptl. characterization of mol. diffusion mechanisms during the unique process of NGA. This includes the observation of a 4-fold decrease of diffusivity within a less than 2 kPa gas pressure variation, corresponding to the NGA transition point. In addition to this study using 3,6-Dibromo-9H-carbazole, there are many other studies that have used 3,6-Dibromo-9H-carbazole(cas: 6825-20-3SDS of cas: 6825-20-3) was used in this study.
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a pharmaceutical intermediate, and also an important intermediate of synthesizing optoelectronic materials. It has been used as a reagent in the synthesis of P7C3-A20 which is a potent neuroprotective agent.SDS of cas: 6825-20-3
