Hydrogels that are mechanically tough and capable of strong underwater adhesion can lead to a paradigm shift in the design adhesives for variety biomedical applications. We hereby innovatively develop facile but efficient strategy prepare hydrogel with instant adhesion, on-demand detachment, high toughness, notch-insensitivity, self-healability, low swelling index, tailorable surface topography. Specifically, polymerization lyophilization conjugation fabrication method was proposed introduce...
A flexible polydentate Salamo-Salen-Salamo hybrid ligand H4L was designed and synthesized, which has rich pockets (salamo salen pockets) so that it may have fascinating coordination patterns with transition metal(II) ions. Four multinuclear complexes, novel butterfly-shaped homotetranuclear [Ni4(L)(μ1-OAc)2(μ1,3-OAc)2(H2O)0.5(CH3CH2OH)3.5]·4CH3CH2OH (1), helical homotrinuclear [Zn3(L)(μ1-OAc)2]·2CH3CH2OH (2), double-helical [Cu2(H2L)2]·2CH3CN (3), mononuclear [Ni(H2L)]·1.5CH3COCH3 (4), been...
Rare homodinuclear Co (II) complex [Co 2 (L)NO 3 ] ( 1 ) and helical centrosymmetric homotetranuclear Cu [Cu 4 (L) (H O) ]·2ClO ), have been synthesized by a newly explored bis (salamo)‐like tetraoxime ligand L) with (NO ·6H O (ClO O, respectively, characterized elemental analyses, IR, UV–Vis spectroscopy single crystal X‐ray crystallography. crystallographic studies indicate that the two atoms (Co1 Co2) in different N coordination spheres, distorted octahedral (Co1) slightly triangular...
Three rare heteromultinuclear complexes, ∞ [NiL(4,4′‐bipy)Pr (NO 3 ) ]·(CH 2 CHOH ( 1 ), [{CuLSm } (4,4′‐bipy)]·CH OH and [{CuL (CH CH OH)Eu ] with a symmetrical salamo‐like hexadentate ligand H L have been synthesized, characterized by FT‐IR, UV–vis X‐ray crystallography. Complex is 1D coordination polymer constructed from heterobimetallic [Ni(L)Pr units which are connected the exo‐dentate 4,4′‐bipy bearing nitrogen‐donor atoms. heterotetranuclear dimer based on [Cu(L)Sm moieties linked...
The coordination behaviors of asymmetric quinoline-decorated half-salamo-type ligand HL1 with Cu(NO3)2·3H2O and Cu(OAc)2·H2O were studied. Two Cu(II) complexes, [Cu(L1)(NO3)]·CH3CH2OH (1) [Cu2(L2)2] (2), isolated characterized by X-ray crystallography, FTIR, UV–vis, fluorescence spectroscopies. Structural analyses showed that 1 is a mononuclear species, whereas 2 binuclear entity. Spontaneous cleavage along the oxime N-O bond close to quinoline ring occurred upon reaction Cu(OAc)2·H2O,...
An unexpected dinuclear Cu(II) complex, [Cu2(L2)2], has been synthesized via complexation of acetate monohydrate with a bis(Salamo) ligand H2L1. Catalysis ions results in cleavage two N–O bonds H2L1, giving dialkoxo-bridged complex. Each complex possesses Cu–O–Cu–O four-membered ring instead the usual [Cu2L1] The H2L1 molecule is stabilized by intramolecular O1–H1⋯N1 hydrogen and π⋯π stacking interactions linking adjacent molecules into 1-D infinite zigzag chain. In structure intermolecular...
