A ‘preporous’ waterwheel-like molecular cage, noria, was knitted with rigid aromatic linkers to obtain porous organic polymers exhibiting excellent catalytic activity toward CO2 fixation and nitroarene reduction.

A series of copper(II)‐Schiff bases‐functionalized polyacrylonitrile fiber catalysts were successfully prepared using copper acetate as copper source and characterized by elemental analysis, fourier‐transfer infrared spectroscopy, ultraviolet‐visible spectroscopy, X‐ray photoelectron spectroscopy and inductively coupled plasma analysis. Excellent physical strength and thermal stability of the fiber

their variety coordination abilities. Interestingly, certain structures exhibit an isomerism effect (L1T-L3T) in the benzotriazole unit when in solid state; a series of studies are indicative of the 1,1-form which is generally dominant in solution even in cases where the crystal structure does not contain this tautomer. The homogeneous catalytic efficacy of all compounds against the well-known multicomponent
在这项工作中,我们研究了一系列基于半刚性苯并三唑的配体(L 1 –L 3)的配位化学,以及低配位数但用途广泛的Ag I离子。这导致了九种新的配位化合物[Ag(L 1)(CF 3 CO 2)](1),[Ag 2(L 1T)2(CF 3 SO 3)2 ]·2Me 2 CO(2), [Ag(L 2T)(ClO 4)(Me 2 CO)](3),[Ag(L 2T)(BF4)(Et 2 O)](4),[Ag 2(L 3T)2(ClO 4)2 ] 2(5),[Ag(L 3)(NO 3)](6),[Ag 2( L 3T)2(CF 3 CO 2)2 ](7),[Ag 2(L 3T)(CF 3 SO 3)2 ](8)和[Ag 2(L 3T)2(CF 3 CF 2 CO 2)2 ]·2Me 2 CO(9)。这些化合物显示出结构的多样性,包括二聚体(5,7,9)和一维(1D)(3,4,6)和二维(2D)(1,2,

Two copper(II) complexes with benzotriazole‐based ligands having pyridyl and quinolinyl arms were synthesized in good yields and characterized fully via spectroscopic and crystallographic techniques. The crystalstructures of the complexes revealed different coordination environments around copper(II) centers. The difference in structure was due to the steric effect of the ligands, which resulted in
