An abnormal threefold interpenetrated diamond-like network formed by assembly of H_2BOPTC~(2-) with DABCOH~(2+) _2: A new route for the construction of diamond-like SOFs

摘要

Solvothermal reaction of H_4BOPTC and DABCO afforded a supramolecular organic framework (SOF), formulated as [DABCOH~(2+) _2]·[H_2BOPTC~(2-)] (1) [1,4-diazabicyclo[2. 2.2]octane (DABCO) and benzophenone-3,3′,4,4′-tetracarboxylic acid (H_4BOPTC)]. The structure of 1 was characterised by elemental analysis, IR and single-crystal X-ray diffraction. It reveals that self-assembly of H_2BOPTC~(2-) forms (6.3) nets and the nets connect to linear spacer DABCOH~(2+) _2 to give an abnormal threefold interpenetrated diamond-like framework, which demonstrates a new route and expands the selection of tectons for constructing diamond-like SOFs. The thermal stability and photoluminescent property of 1 have also been investigated.
