On metal-organic framework isomers, and the SF6 sorption and fluorescence of an In and a Zr MOF with a tritopic linker

Abstract

The concept of framework isomers by network topology analysis is illustrated by a new rod-MOF isomer of In3+ and the tritopic linker 4,4’,4’’-(benzene-1,3,5-triyl-tris(oxy))tribenzoic acid (H3bttb), CTH-41, with a unique 3- and 4-connected net different from 437-MOF. CTH-41 shows affinity for SF6 with a Langmuir area of 1587 m2/g while the new Zr4+ dot-MOF with the same linker [Zr6(bttb)4(O)4(OH)4] CTH-42, forms the 3-, 12-connected llj-net based on a different conformation of the flexible bttb linker.
