  Synthesis and mesomorphic properties of new fluorinated hydrogen-bonded supramolecular liquid crystals

  摘要：

  A series of fluorinated benzoic acid-pyridine supramolecular liquid crystals and their non-fluorinated analogues were synthesized and studied by use of polarizing optical microscopy (POM), differential scanning calorimetry, and X-ray diffraction. A smectic phase was identified for the fluorine-bearing products, with high clear points, and two peaks (2 theta a parts per thousand 6.5A degrees, 24A degrees) in X-ray diffraction. However, non-fluorinated analogues have a nematic phase with low clear points and one peak (2 theta a parts per thousand 23A degrees) in X-ray diffraction. This indicates that one trifluoromethyl is able to increase stability and the degree of order of hydrogen-bonded supramolecular liquid crystals..

  Properties of liquid crystals and Cu²⁺ recognition based on Schiff bases

  摘要：

  Two series of new Schiff base compounds were synthesized. For Schiff base compounds with a pyridine nitrogen atom in 4-position (7a-e), their supramolecular hydrogen bonding complexes show good liquid crystal properties. However, no liquid crystal property is observed for 8a-e. Results of theoretical calculations demonstrate that it is the intermolecular hydrogen bond of Schiff base compounds (8a-e) that prevents the formation of supramolecular hydrogen bonding. The Schiff base compounds, with terminal alkoxy chains, can recognize Cu2+ selectively with a color change. Nevertheless, others cannot recognize Cu2+.

  corresponding L (n = 8, 14) ligands with [RhCl(COD)]2. They react with CO to give cis-[RhCl(CO)2L] (n = 2, 4, 6–10, 12, 14). Reaction of cis-dicarbonyl compounds with L in the presence of Me3NO gives trans-[RhCl(CO)L2] (n = 4, 8). Monocarbonyl compounds of formulae [RhCl(CO)L(P(OMe)3)] (n = 6, 8, 14) have been made by reaction of cis-[RhCl(CO)2L] with P(OMe)3 in dichloromethane. The mesogenic properties of

  Rh(OCOCR3)(cod)L(n) (1-6) and cis-Rh(OCOCR3)(CO)2L(n) (7-12) (R = H, F; cod = 1,5-cycloctadiene; L(n) = NC5H4CH = NC6H4OC(n)H2n+1 with n = 2, 8, 14) complexes have been prepared by the reaction of the L(n) ligands with the corresponding dimers [Rh(OOCCR3)(cod)]2 or [Rh(OOCCR3)(CO)2]2 (R = H, F). The cis-dicarbonyl compounds 7-12 decompose in dichloromethane solution to form square-planar clusters of 64 electrons, Rh4(OOCCH3)4(CO)4L4n (13-18). The molecular structure of Rh4(OOCCH3)4(CO)4L4(14) (15) has been determined by X-ray investigation. The complex is centrosymmetric, and the four rhodium atoms define a rectangle. Two alternant metal-metal bonds of the rectangle are bridged by two carbonyl groups; the other two remaining Rh-Rh bonds are bridged by two acetate groups. Each metal completes its coordination sphere with the pyridinic ligand NC5H4CH = NC6H4OC14H29.

The complexes [Rh4(OOCCH3)4(CO)4(py)4] (19, 20; R = H, F; py = pyridine) are also reported.
