Self-assembly of columnar mesophases from diaminotriazines

Diaminotriazines are known to self-associate in solution, in the solid state, and on surfaces via characteristic hydrogen bonding motifs. Although complementary hydrogen bonding between diaminotriazine derivatives and carboxylic acids has been shown to induce mesomorphic properties, the hydrogen-bonded self-association of diaminotriazines to form liquid crystalline phases has not been reported. Here, we describe the synthesis and mesophase characterization of biphenyldiaminotriazines bearing one alkoxy side-chain (compound 3) or two alkoxy side-chains (compound 2). Although compound 3 does not show any mesomorphism, derivatives of compound 2 exhibit thermotropic columnar mesophases as shown by polarized optical microscopy, differential scanning calorimetry, and variable-temperature X-ray powder diffraction. The results are consistent with self-assembly of a hexameric hydrogen-bonded rosette that can stack to form columnar mesophases, suggesting that the association of diaminotriazines by hydrogen bonding can play an important role in directing molecular organization in liquid crystalline phases.

Enthalpy-entropy compensation combined with cohesive free-energy densities for tuning the melting temperatures of cyanobiphenyl derivatives

This work illustrates how minor structural perturbations produced by methylation of 4′-(dodecyloxy)-4-cyanobiphenyl leads to enthalpy-entropy compensation for their melting processes, a trend which can be analyzed within the frame of a simple intermolecular cohesive model. The transformation of the melting thermodynamic parameters collected at variable temperatures into cohesive free-energy densities expressed at a common reference temperature results in a novel linear correlation, from which melting temperatures can be simply predicted from molecular volumes. In tune with temperature! The transformation of the melting thermodynamic parameters into cohesive free-energy densities (CFED) for 4′-(n-oxy)-i′-methyl-j-methyl-4-cyanobiphenyl (CnLi′,j) provides a novel linear correlation for predicting melting temperatures in a simple way.

Siloxane-supported organometallic compounds and their catalytic activities for the hydrosilylation of vinylsilanes and dienes

Two different classes of silicone-modified ligands were prepared: nitrile derivatives, 4′-[3-(organosilyl)propoxy]-biphenyl-4-carbonitrile R′3SiC3H6OC6H 4C6H4CN 2 (R′3Si- = a: Me 3SiOSiMe2-, b: (Me3SiO)2SiMe-, c: Me3SiO(Me2SiO)3SiMe2-, d: Me 3SiO(Me2SiO)25SiMe2-); and, pyridine derivatives, isonicotinic acid 2-methoxy-4-[3-(organosilyl)propyl]phenyl ester R′3SiC 3H6Ph(OMe)OC(O)C5H4N 6. Compounds 2 and 6 were bound to Pd and Pt using ligand substitution reactions with organometallic precursors to give (R3SiC3H 6OC6H4C6H4CN) 2PdCl2 3, (R3SiC3H 6OC6H4C6H4CN) 2PtCl2 4 and (R3SiC3H 6C6H3(OMe)OC(O)C5H 4N)PtCl2(η2-1-octene) 8. The polydimethylsiloxane (PDMS)-supported Pt and Pd compounds 3d and 4d had excellent solubility in both organic solvents and polysiloxanes. All the Pt compounds exhibited good catalytic activity for hydrosilylation of vinylsilanes. The PDMS-supported Pd compound 3d also was effective catalyst for hydrosilylation of a diene, isoprene, with 1,1,1,3,3-pentamethyldisiloxane MMH to produce the 1,4-adduct Me3SiOSiMe 2CH2CH=CMeCH2-H as a major product.

Thermal and Ferroelectric Properties of Novel Ferroelectric Liquid Crystals Containing α-Methylcinnamoyl Moiety in the Core Structure

Six homologous series of novel ferroelectric liquid crystals containing α-methylcinnamoyl moiety in the core structure: have been synthesized and their thermal and ferroelectric properties have been investigated.The mesomorphic transition temperatures and the spontaneous polarization for the homologous series (IA, IB, IIA, IIB, IIIA and IIIB) depend on the core structure, the chiral group, and the terminal alkoxyl chain length.These homologous series show the chiral smectic C phase over wide temperature ranges including room temperature and the values of their maximum spontaneous polarization are in the range of 30 to 800 μC m-2.The thermal stability of the mesophase and the magnitude of the spontaneous polarization have been discussed from the view point of the molecular structure and the local molecular interactions.
