Specifications | MSDS | Literature and Reviews

3,3',6,6'-Tetrabromo-9,9'-bicarbazole (TBBCz), CAS number 18628-03-0, is a bicarbazole that is joined at 9,9'-positions (N-N bonding) with four bromo function groups at 3,3',6,6'-positions. It can be considered as two 3,6-dibromocarbazole joined together to form a butterfly shaped structure with a nitrogen-nitrogen bonding.

Highly stable MOF [Zn₆L₄(Me₂NH₂⁺)₄‧3H₂O], also known as FJU-83 with T-shaped functional capture sites, has been explored for acetylene capture and separation. FJU-83a demonstrated an excellent C₂H₂ uptake capacity of 122.9 cm³/g, plus good C₂H₂/CH₄ and C₂H₂/CO₂ selectivity of 24 and 2.9 respectively, under moderate temperature and normal atmosphere. Studies showed that the high selectivity over C₂H₂ to separate it from CH₄ or CO₂ was originated from the multiple C-H∙∙∙π and π∙∙∙π interactions. Car-CFT-5-500, another microporous bicarbazole-based COF, showed high specific surface area of 1,400 m²/g, a CO₂ uptake capacity of 7.60 mmol/g at 273 K, and a capacitance of 545 F/g at 5 mV/s.
