Novel pyridine-containing macrocyclic compounds, such as 6,12,19,25-tetramethyl-7,11,20,24-dinitrilo-dibenzo [b,m]1,4,12,15-tetra-azacyclodoc osine (TMCD), were synthesized and used as electron transport layer in organic electroluminescent devices. Devices with a structure of glass/indium-tin oxide/arylamine derivative/ tris(quinolinolato)aluminum(Ⅲ) (Alq)/TMCD/LiF/Al exhibited green emission from the Alq layer with external quantum efficiency of 0.84% and luminous efficiency of 1.3 lm/W. The derivatives of TMCD were synthesized and characterized as well. These compounds were also found to be useful as the electron-transporting materials in organic electroluminescent devices. 展开更多

A novel [1+1] Schiff-base macrocyclic compound 3 has been synthesized from precursor 1, 1,3-bis(2'- formylphenoxy)-2-propanol, and precursor 2, resorcinol-bis(4-aminophenyl)ether, via condensation and cyclizaction using Ba2+ as template. The macrocycle 3 was further reduced giving saturated macrocycle 4. The structures of 3 and 4 were characterized by elemental analysis, ~H NMR, IR, and MS spectra, and their structures were determined via single crystal X-ray diffraction studies. X-ray diffraction analysis revealed that the macrocyclic compound 3 has a folded conformation, and the corresponding reduced product 4 adopts a twisted and folded conformation due to its flexible nature. ~ 2013 Bi-Xue Zhu.

A mixed-valence dinuclear manganese complex, [Mn ⅡMn ⅢL](ClO 4)·1/2MeOH, where L is a macrocyclic ligand derived from the cyclocondensation of sodium 2,6-diformyl-4-methylphenolate with N,N-bis(2-aminoethyl)-2-hydroxybenzyl amine, was obtained and its structure was determined by X-ray diffraction. The orange crystal is a monoclinic system with space group P2 1/c and lattice parameters a=1.1617(4), b=1.4005(3), c=1.4641(3) nm, β=113.03(2)°, and Z=2. The crystal structure shows that each pendant-arm is bonded in a bidentate fashion to the adjacent metal atom and that both the arms are on the same side of the macrocycle. The two Mn atoms are bridged by two μ 2-phenoxy oxygen atoms of the tetra-imine macrocycle, and each Mn atom, locating in a trigonal prismatic coordination environment(N 3O 3), is six-coordinated by the two imine nitrogen atoms, one tertiary nitrogen atom and a pendant phenol moiety apart from the two oxygen atoms. 展开更多

Supramolecular polymers, which combined of the supramolecular chemistry and polymer science, are constructed from monomers together by reversible noncovalent interactions. Supramolecular polymers in aqueous solution are especially important due to their superior biocompatibility and environmental adaptation, which determined they have wide applications in various areas, such as drug delivery, selfhealing, shape memory. Macrocyclic compounds, such as cyclodextrins, calixarenes, cucurbiturils and pillar[n]arenes, are the most used building blocks in the preparation of supramolecular polymers.Macrocycle-based supramolecular polymers, which introduce the host-guest interaction in the system,endow these polymers with interesting and smart physical-chemical properties. In this review, we summarized recent studies about supramolecular polymers in aqueous solution based on macrocyclic compounds. 展开更多

General and straightforward synthetic strategy towards the iron(Ⅱ)clathrochelates with functionalizing substituents in their apical capping and one of the three chelate ribbed fragments was developed.Their hexachloroclathrochelate precursors were prepared by the direct template condensation of dichloroglyoxime with a suitable boronic acid on the Fe^(2+) ion as a matrix and underwent a stepwise nucleophilic substitution with S_(2)-,N_(2)- or O_(2)-bis-nucleophiles,forming the alicyclic or aromatic N_(2)-,S_(2)-or O_(2)-six-membered fragments.Depending on the reaction conditions and precursor-to-dinucleophile molar ratios,iron(Ⅱ)clathrochelates with one(S,O and N),two(S,O and N)or three(S and O)X_(2)-six-membered ribbed substituent(s)were obtained.Their reactivity substantially decreases in a row:Cl_(6)-Cage>Cl_(4)X_(2)-Cage(where X=S,O or,especially,N)>Cl_(2)X_(4)-Cage(where X=S or O).The reactive monoribbed-functionalized clathrochelates underwent further chemical transformations giving the target macrobicyclic complexes with terminal vector groups.As follows from the single crystal XRD data,their FeN_(6)-coordination polyhedra possess the geometry intermediate between a trigonal prism and a trigonal antiprism(φ=21.3°—25.20°).Fe-N distances vary from 1.887(6)to 1.933(8)Å.Their 3D-molecules,the hydrophobic–hydrophilic balance in which can be tuned using a ribbed functionalization,form in the crystals the intermolecular specific halogen bonds and/or hydrophobic interactions. 展开更多
