Bis isophthalate

Tetracarboxylate ligands such as 1,2,3,4-cyclobutanetetracarboxylate (190),287 1,3,5,7-adaman-tanetetracarboxylate (191),288 a bis-isophthalate derivative (192),289 (27 ,4i ,6i ,87 )-l,9-dihy-droxy-3,5,7-trioxanonane-2,4,6,8-tetracarboxylate (193),290 and 1,2,4,5-benzenetetracarboxylate (194)291 have been synthesized and applied as building blocks in open-metal-site porous materials. 

Self-assembled macromolecular structures are of particular interest because of their ability to reorganize in response to changes in their environment (concentration, solvent, pH, etc.)415-416 Zimmerman and co-workers417 418 first demonstrated the hydrogen-bond mediated self-assembly of dendritic cores (Figure 22) in 1996. The rigid bis(isophthalic acid)...
