dc.description.abstractHighly volatile and toxic bromine (Br-2) molecules can be utilized safely in various chemical processes when coupled with efficient separation systems. Herein, we present two different N-containing porous organic cages (POCs), covalent cage 3-R (CC3-R) and formaldehyde tied-reduced covalent cage 3 (FT-RCC3), for vapor Br-2 capture under ambient conditions. They show outstanding sorption capacities (11.02 mmol g(-1) and 11.64 mmol g(-1), respectively) compared with previously reported adsorbents. Reversibility of the Br-2 sorption process has been elucidated experimentally and computationally by identifying bromine species adsorbed at POCs and calculating their binding energies. The strong charge-transfer interactions between adsorbed Br-2 and abundant N atomic sites of the host cages led to the dominant formation of polybromide species (Br-3(-) and Br-5(-)). Further host-guest interaction between POCs and polybromides determined the reversibility of the Br-2 sorption process-showing partially reversible (>70% recovery) behavior for CC3-R and irreversible (<10% recovery) behavior for FT-RCC3, both of which were affected by the chemical and structural nature of different POCs. DFT calculations further indicate that the formation of carbocationic species (Br-3(-) and Br-5(-)) and HBr is energetically favorable within the cage, which is in good agreement with the experimental results. This work demonstrates that strong host-guest interactions are essential for highly efficient Br-2 capture and storage performance.-
