New Three-Dimensional Supramolecular Framework: Crystal Structure and Photocatalytic Property

In this work, benzimidazole (Hbim) and Cu(II) ions ligands were chosen as building blocks to produce a novel Cu(II) compound (CP) based on {Cu4O}cluster, namely, [Cu4OCl6(Hbim)4]n·n(H2O)·2n(EtOH) (1). The investigation of SCXRD reveals that the CP 1 is a separated 0D structure based on tetrahedral {Cu4O} clusters. Furthermore, this supramolecular frame displayed superior photocatalytic effect on the photodegradation of MB under UV light irradiation.

A Co(II) compound: photocatalytic activity and application value in trigeminal neuralgia with minimally invasive interventional therapy guided by CT

A new thermostable Co(II)-based compound, namely [Co₃(L)₂(HTEA)₂]_n (1, HL = isonicotinic acid, H₃TEA = triethanolamine), has been successfully synthesized by the isomicotinic acid ligand and HTEA anion. The photocatalytic property of 1 was also investigated, indicating that it shows excellent photocatalytic activity for the degradation of Rhodamine B (MB) solution under the UV light irradiation. For the treatment of trigeminal neuralgia, the content of the inflammatory cytokines released into the trigeminal ganglion tissue fluid was measured with enzyme-linked immunosorbent assay (ELISA) assay. Then, the real-time Reverse Transcription-Polymerase Chain Reaction (RT-PCR) was conducted and the activation of the nuclear factor kappa-B (NF-κB) inflammatory signaling pathway was measured.

Fresh hetero-metallic compound as luminescent sensor for detection of CS2 and inhibitory activity on children diabetes

The combination of the dicarboxylate ligand of 2-aminoterephthalic acid (H₂L), Cd(NO₃)₂·4H₂O, and KNO₃ under hydrothermal condition formed a fresh hetero-metallic coordination polymer, namely, [CdK₂(L)₂(H₂O)₄]_n (1). The compound exhibited a high luminescence intensity at normal environment as well as high sensitivity and selectivity in the measurement of CS₂. The effect of the fresh compound on childhood diabetes was investigated. A blood glucose monitor was utilized to assess the blood glucose level of the body after the addition of the compound. Moreover, the relative expression level of the insulin recipient on hepatocytes was assessed by real time RT-PCR.

New 3D Supramolecular Framework: Photocatalytic Property and Therapeutic Activity on Orbital Wall Fracture

Coordination compounds have undergone booming development in the past 20 years for their applications as multifunctional materials in the field of catalysis and biomedicine. To create compounds with both catalytic and bioactive properties, we selected Cu(II) ion and benzimidazole (Hbim) ligand as the building blocks to fabricate a new cluster-based Cu(II) compound [Cu4OCl6(Hbim)4]n·n(H2O)·2n(EtOH) (1). The exploration of single crystal X-ray diffraction exhibits that complex 1 is a 0D isolated structure on the basis of tetrahedral {Cu4O} clusters. Moreover, such supramolecular framework not only shows excellent photocatalytic effect for the MB photodegradation under the irradiation of ultraviolet light but also has the application values against orbital wall fracture. This work gives new insights on the creation of coordination polymers which might be potentially used as photocatalytic and bioactive reagents.
