  Benzimidazole-Based Tripodal Receptor:  Highly Selective Fluorescent Chemosensor for Iodide in Aqueous Solution

  摘要：

  We synthesized a novel tripodal fluorescent receptor bearing benzimidazole motifs as recognition sites in the pods of the receptor. The recognition behavior of the receptor toward various anions was evaluated in CH3CN/H2O (9:1, v/v) solution. The receptor showed changes in fluorescent intensity only with I-, but it showed no significant changes on addition of other anions such as F-, Cl-, Br-, HSO4-, NO3-, CH3COO-, and H2PO4-.

• Complexation properties of a heteroditopic cryptand towards CuII and NiII, crystal structures of the cryptand and its nickel(II) cascade complex

  The crystal structure of the heteroditopic cryptand (L) formed by Schiff-base condensation of tris(2-aminoethyl)amine and 2,2′,2″-nitrilotris(ethyleneoxy)tris(benzaldehyde) followed by reduction with NaBH 4 has been determined. The molecule has an endo-endo conformation with a pseudo-three-fold symmetry axis passing through the two bridgehead nitrogens. This symmetry is maintained in chloroform solution as indicated by its 1 H NMR spectrum. The cryptand accepts a metal ion (Cu II , Zn II or Ni II ) inside the cavity forming mononuclear cryptates of general formula [ML][ClO 4 ] 2 . The metal ion occupies the N 4 end of the cavity. The light blue CuN 4 chromophore thus formed exhibits an axial EPR spectrum with very small A ∥ value (63 × 10 -4 cm -1 ) and a low-energy ligand-field band. Nickel(II) initially forms a blue [NiL][ClO 4 ] 2 complex which on dissolving in moist MeCN solution crystallizes as purple rectangular parallelopipeds with the formulation [NiL(H 2 O)(MeCN)][ClO 4 ] 2 ·H 2 O·2MeCN. The crystal structure of this complex has also been determined. The Ni II ion is octahedrally co-ordinated with the equatorial sites occupied by the three secondary amino N atoms of the cryptand and the N atom of the bound MeCN. The axial sites are occupied by the bridgehead N and the O atom of the water molecule which enters the cavity forming a cascade complex.

  通过Schiff-base缩合反应形成的异双齿穴醚(L)的晶体结构，由三(2-氨基乙基)胺和2,2′,2″-氮三(乙烯氧基)三(苯甲醛)组成，随后用NaBH4还原，已被确定。该分子具有endo-endo构型，通过两个桥头氮原子存在一个伪三重对称轴。这种对称性在氯仿溶液中得到保持，如1H NMR谱所示。该穴醚在腔内接受金属离子(Cu II、Zn II或Ni II)，形成通式为[ML][ClO4]2的单核穴合物。金属离子占据腔内N4端。形成的CuN4光蓝色素表现出轴向EPR谱，具有非常小的A∥值(63 × 10-4 cm-1)和低能量配体场带。镍(II)最初形成蓝色的[NiL][ClO4]2配合物，在湿润的MeCN溶液中溶解后结晶为紫色矩形平行六面体，具有配方[NiL(H2O)(MeCN)][ClO4]2·H2O·2MeCN。该配合物的晶体结构也已被确定。Ni II离子是八面体配位的，赤道位点由穴醚的三个二级氨基N原子和结合的MeCN的N原子占据。轴向位点由桥头N和进入腔内的水分子形成瀑布型配合物的O原子占据。

  A new heteroditopic cryptand (L) has been synthesized in high yields, at 5 °C and in absence of any templating metal ion, by tripod–tripod Schiff-base condensation of tris(3-aminopropyl)amine and 2,2′,2″-nitrilotris(ethyleneoxy)tris(benzaldehyde) followed by reduction in situ with NaBH 4 . The molecule has an endo-endo conformation with a distance of 5.291 Å between the two bridgehead nitrogens. The cryptand forms mononuclear cryptates of the general formula [ML][ClO 4 ] 2 with copper(II) and zinc(II) perchlorates. The crystal structure of [ZnL][ClO 4 ] 2 ·2H 2 O was determined. The Zn II occupies the N 4 end of the cavity in an almost ideal tetrahedral geometry. The blue copper(II) cryptate exhibits ligand-field bands at 875 and 745 nm and a ligand-to-metal charge transfer at 275 nm in acetonitrile solution at 298 K indicative of pseudo-tetrahedral CuN 4 co-ordination. However, its EPR spectral characteristics in the solid state or in solution are typical of a magnetically concentrated complex.

  series of novel tripodal colorimetric anion sensors based on hydrazone CHNNH groups have been synthesized and their recognition behavior with anionic guests has been studied. In DMSO solutions, sensors 1 and 2 show colorimetric responses for F−, H2PO−4 and AcO−, while in DMSO/H2O (9:1, V/V) solutions, sensor 1 shows single selectivity for AcO−. 1H NMR titration confirms that the tripodal sensors could

• Toward dynamic combinatorial libraries of cryptands

  日期：2011.8

  The first examples of dynamic combinatorial libraries of cryptands, created using the chemistry of imines is presented. Experiments, in which two trialdehydes compete for one triamine in a small library, show the full reversibility of cryptand formation, since the library composition is the same irrespective of the sequence of introducing the building blocks to the mixture.
