To investigate the influence of different 5-functionalized isophthalate ligands on the self-assembly and structures of Zn(II)-based coordination polymers (CPs), we selected four 5-functionalized isophthalate ligands coordinated with 4,4′-bipyridyl (bpy) and Zn(II) salt, and four new CPs, namely, [Zn(EtOip)(bpy)]·2H2O}n (1), [Zn(PrOip)(bpy)]·2H2O}n (2), [Zn(nBuOip)(bpy)]n (3) and [Zn(nPeOip)(bpy)]n
为了研究不同的 5-官能化间苯二甲酸酯配体对 Zn( II ) 基配位聚合物 (CPs) 自组装和结构的影响,我们选择了四种与 4,4'-联吡啶 (bpy) 配位的 5-官能化间苯二甲酸酯配体和Zn( II )盐,以及四个新的CP,即[Zn(EtOip)(bpy)]·2H 2 O} n ( 1 )、[Zn(PrOip)(bpy)]·2H 2 O} n ( 2 ), [Zn( n BuOip)(bpy)] n ( 3 ) 和 [Zn( n PeOip)(bpy)] n ( 4 ) (其中 EtOip = 5-乙氧基间苯二甲酸酯, PrOip = 5- n-丙氧基间苯二甲酸酯、n BuOip = 5-正丁氧基间苯二甲酸酯和n PeOip = 5-正戊氧基间苯二甲酸酯)是在水热条件下制备的。此外,我们考虑改变 N-配体的特征(长度),这有望改变所得 CP 的结构多样性和性质。我们用 1,2-

A novel optical-isomer separating agent for chromatography is provided which has, as a chiral selector, a macrocyclic amide compound having the ability to function as a chiral shift agent. The optical-isomer separating agent for chromatography is formed by bonding, with a carrier by chemical bonding, a specific ring structure containing an asymmetry recognition site, an amide group as a hydrogen-bond donor site, and a hydrogen-bond acceptor site.
ne (bpp) ligand. Topology analysis indicated that compound 1 showed a 3D lvt topology, whereas compound 2 showed a two-fold interpenetrated 3D diamond network. Complexes 3 and 4 exhibited 2D sql/Shubnikov tetragonal plane networks. The coordination polymers were distinguished by the 5-substituted groups of isophthalate and the conformation of bpp. Moreover, compounds 2–4 are bifunctional luminescent

Compounds, compositions, and methods comprising a polyamine compound are described, which may be used to kill, disperse, treat, or reduce biofilms, or to inhibit or substantially prevent biofilm formation. In certain aspects, the present invention relates to compounds, compositions, and methods comprising polyamine compounds that have antimicrobial or dispersing activity against a variety of bacterial strains capable of forming biofilms.
R-Substituent-Induced Structural Diversity and Single-Crystal to Single-Crystal Transformation of Coordination Polymers: Synthesis, Luminescence, and Magnetic Behaviors
that substitutions of isophthalic acid ligands with different lengths exert significant effects on the architecture of the CPs. Besides, the fluorescent properties of 1–6 were also investigated. The magnetic measurements indicate that CP 7 exhibits weak antiferromagnetic interactions, and CPs 8–10 exhibit weak ferromagnetic interactions within the binuclear (CoII)2 units.
