H4BOPTC reacts with IMI to yield a supramolecular organic framework, formulated as [IMIH+](2)[H2BOPTC2-]0.5H(2)O (1) (IMI=imidazole, H4BOPTC=benzophenone-3,3,4,4-tetracarboxylic acid). Single-crystal X-ray diffraction analysis reveals that 1 shows a novel architecture with two-level hierarchical entanglement. H2BOPTC2- connects to IMIH+ through hydrogen bonds, providing 1D ribbon. The basic ribbons are entangled into a 3D net with ant topology. Then the ant nets further interpenetrate to give the final entangled framework. The thermal stability, optical band gap energy and photoluminescent property of 1 have also been investigated.
