The article conveys some information:
Two-dimensional (2-D) coordination polymers [Zn2(bpab)(CH3CO2)4]·H2O (1), [Zn(bpab)(H2O)2](NO3)2 (2), [Cu2(bpab)I2]·CH3OH (3), and [Cu2(tpmd)I2] (4) have been synthesized by the reaction of zinc(II)/copper(I) ions and tetradentate polypyridine ligands (bpab = bis-1,4-(di-4-pyridylaminomethyl)benzene and tpmd = N,N,N’,N’-tetrakis(pyridine-4-yl)methanediamine). The zinc(II) ions of 1 and 2 have distorted tetrahedral and trigonal bipyramidal geometries, resp. By coordinating zinc(II) ions and bpab ligands, 1 and 2 formed a brick wall and puckered 2-D networks, resp. The copper(I) ions of 3 and 4 are both tetrahedral structures with Cu2I2 rhomboidal geometry. By linking the Cu2I2 cores and bpab/tpmd ligands, 3 and 4 exhibited interwoven and interconnected bilayered 2-D networks, resp. Compared to free bpab and tpmd ligands, polymers 1 and 2 show strongly blue-shifted emissions, whereas polymers 3 and 4 show strongly red-shifted emissions. Therefore, the shifts of emission wavelengths are strongly dependent on the zinc(II) and copper(I) ions that linked the bpab/tpmd tetradentate ligands, resp. In the experimental materials used by the author, we found 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Recommanded Product: 623-24-5)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Most of the natural organobromine compounds are produced by marine organisms , and several brominated metabolites with antibacterial , antitumor , antiviral , and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. Recommanded Product: 623-24-5 In contrast, terrestrial plants account only for a few bromine-containing compounds.
