Potential Application Values of Two Multicoloured Coordination Compounds as Multicolor Luminescent Materials

Two Co(II)-based coordination compounds, namely {[Co(apc)2]·H2O}n (1) and [Co(apc)2(H2O)2] (2), have been successfully prepared via reaction of a multifunctional ligand 2-aminopyrimidine-5-carboxylic acid (Hapc) with Co(NO3)2·6H2O based on different reaction environments. Both compounds were studied via elemental analysis (EA), single crystal X-ray diffraction analysis (SC-XRD), thermogravimetric analysis (TG), powder X-ray diffraction (PXRD) and infrared spectroscopy (IR). Fluorescence spectroscopy was employed to analyze the fluorescence properties of the ligand and the two compounds. The results revealed that the two compounds exhibited green and blue fluorescence, surpassing the original ligand in terms of properties. Based on the distinct fluorescence colors of the two compounds, there is potential to create multicolored fluorescent materials by adjusting their material ratios. This prospect could further extend their applications in the field of fluorescent materials.

Improvement of two Mn2+ coordination polymers on cognitive function of aged rats after anesthesia

Two Mn²⁺ coordination polymers (CPs) with the scientific terms of {[Mn(TTPA)·(H₂O)₂]·H₂O}_n (1) and {[Mn(TTPA)·(H₂TTPA)]·2DMSO}_n (2) were favorably created on the basis of multidentate linking organic ligand 2,5-bis-(1,2,4-triazol-1-yl)-terephthalic acid (H₂TTPA) in the conditions of solvent-presupposed thermal reaction. To measure the influence of two Mn²⁺ coordination polymers with novel structures, the ELISA assay and real-time RT-PCR assay were conducted in this present research. First of all, the ELISA assay was conducted to measure the content of inflammatory cytokines released into the hippocampal tissue. In addition to this, the relative expression of the TAU protein in the brain was further determined with real-time RT-PCR assay.
