WebNov 6, 2015 · Polycarboxylate ligands, as good candidates for the construction of CPs and MOFs, have attracted much interest from chemists. For example, 3,3′,4,4′-biphenyltetracarboxylic acid (H 4 bptc) has been employed as exo-multidentate ligand for the design and construction of novel compounds with high thermal stability and symmetry . WebSep 1, 2000 · Among them, 3,3′,4,4′-biphenyltetracarboxylic dianhydride (s-BPDA) was commercialized in the early 1980s and is widely used at present [5]. In contrast, an isomeric 2,2′,3,3′-biphenyltetracarboxylic dianhydride (i-BPDA) attracted much less attention, with only two publications in the open literature being found to date [6] , [7] .
