Syntheses, structures and photoelectronic properties of a series of tri- and tetra-nuclear metal complexes based on a 36-membered tetraphenol macrocyclic ligand

摘要: Abstract In this article, tetranuclear ZnII coordination complexes [Zn4L(μ2-OH)2]·2(NO3)·6(CH3OH)·H2O (1) and [Zn4L(μ2-OH)2(H2O)2]·(p-bdc)·2(CH3OH)·3H2O (2), dinuclear complex [Zn4L(NH2-bdc)2]·2(CH3OH)·3H2O (3), trinuclear CdII [Cd3L(m-bdc)]·6.5H2O (4) [Cd3L(NH2-bdc)]·5.5H2O (5), based on a tetraphenol 36-membered macrocycle (L) having four ethylenediamine 2,6-diformyl-4-methylphenol functionalities, have been synthesized at room temperature (p-bdc = 1,4-benzenedicarboxylate, NH2-bdc = 5-aminoisophthalate m-bdc = 1,3-benzenedicarboxylate). 1 2, centers are bridged by phenoxide hydroxy atoms of the L ligands to form complexes. The inorganic organic anions in 2 do not coordinate centers, but act as counter anions. 3, two O cluster (Zn2O2N4). Moreover, (Zn2O2N4) clusters within ring ligand further NH2-bdc monodentate fashion. Compound 4 possesses (Cd3N8O8), which has similar structure compound 5. dicarboxylate yield an infinite polymers chain. photoelectric transfer properties 1, were investigated surface photovoltage spectroscopy (SPS) field-induced spectra (FISPS) techniques. results reveal that exhibit positive (SPV) responses range 300–600 nm, possessing p-type semiconductor characteristics. So far, macrocyclic for first time. elemental analyses, IR spectra, luminescent these compounds also studied.
