Design, synthesis, and characterization of 1,3,5-Tri(1 H-benzo[d]imidazol-2-yl)benzene-based fluorescent supramolecular columnar liquid crystals with a broad mesomorphic range

A new kind of supramolecular columnar liquid crystal T-A with a broad mesomorphic range (up to 164.9 °C), good thermal stability, and strong fluorescence is designed and formed by the H-bonding between 1,3,5-tri(1H-benzo[d]imidazol-2-yl)benzene (T) and serial gallic acid derivatives (A). Two components are easily available because of simple routes, common reactions, high yields, commercial starting materials, and inexpensive catalysts. The introduction of the 1,2,3-triazole structure into component A makes the textures different and is slightly disadvantageous for the T-A complexes.

Synthesis and self-assembly of aroylhydrazone based polycatenars: A structure-property correlation

Two series of aroylhydrazone based polycatenars which differ from each other in terms of the linking groups (semi flexible ester or flexible ether linkage) were synthesized. These hexacatenars were mesogenic and also showed gelation in organic solvents at

Effect of the linkages on the self-assembly and photophysical properties of 4,7-diphenyl-2,1,3-benzothiadiazole-based luminescent polycatenars

Three series of 4,7-diphenyl-2,1,3-benzothiadiazole (DBTD)based polycatenars containing a central 4,7-diphenyl-2,1,3-benzothiadiazole moiety connected to 3,4,5-trialkoxyl benzene units at both ends through ether (-OCH2-), ester (-OOC-)or amide (-HNCO-)linkages were synthesized via Suzuki coupling reaction as key step. The polarities of the linkages had great effect on their self-assembly and photophycial properties. Both ether and amide compounds were mesogens, while the ester compounds were non-mesogens. The ether compounds displayed Colhex/p6mm phases, while the amide compound displayed two kinds of columnar phases i.e. columnar rectangular phase with p2mm and columnar hexagonal phase with p6mm lattices depending on temperature. The column phases could be aligned in electric field or under mechanical shearing. The ether and amide compounds showed the significant red-shifted maximum absorption and emission. In the solid and gel states, both ether and amide compounds were yellow luminescence, while ester compounds were green luminescence.

Triketonate difluoroboron complexes. Substitution-dependent liquid crystal and photophysical properties

Novel alkyloxyphenyl-substituted β,δ-triketonate difluoroboron complexes have been efficiently synthesised and thoroughly characterised. Significant features such as liquid crystal behaviour and solid and solution fluorescence are observed in all cases. The mesomorphism was determined by the presence of one, two or three alkyl chains in each substituent aromatic group of the triketonate ligand. So, smectic C mesophases were found for compounds carrying two lateral chains, each of them located at one of each phenyl substituent, while the presence of four or six chains at the whole molecule gave rise to smectic A or discotic lamellar and hexagonal columnar mesophases, respectively. Fluorescence in the solid state and in solution is again proved to be dependent on the ligand substitution as well as to be maintained in the mesophase. These multifunctional materials also present luminescent sensor activity towards Hg2+ and Cu2+.

Cubic phase formation from new hexacatenar metallomesogens based on cobalt 3,4,5-trialkoxybenzoate

Cobalt complexes of Co(3Cn)2(MeOH)4, derived from 3,4,5-trialkyloxybenzoate ligand (noted as 3Cn) with n = 10, 12, 14 and 16, were synthesized and characterized. The crystal of Co(1C12)2(MeOH)4 were determined by means of x-ray single crystal analysis. It crystallizes in the monoclinic P21/c space group with a = 24.3271(19) ?, b = 14.0058(11) ?, c = 6.4612(4) ?, α = γ = 90o, β = 94.368(4)o, and Z = 2. The phase texture and mesogenic properties were detected by polarized optical microscopic and powder x-ray diffraction technique. It was found that these compounds display the cubic phases. Differential scanning calorimetric data indicated that these compounds were nearly room temperature liquid crystalline and with a very wide mesogenic phase range. Two 3,4,5-trialkyloxybenzaotes were coordinated to a cobalt ion to form novel hexacatenar metallomesogens. The solid-state structure confirmed that two monodentate carboxylate ligands and four methanol molecules coordinated to the cobalt ion to give a slight distorted octahedral geometry. The mesomorphic behavior are stable and exist over a wide temperature range, which is arranged in layers and exhibited enantiotropic cubic mesophase.

Supramolecular interactions of high molecular weight poly(2,7-carbazole)s with single-walled carbon nanotubes

A novel 2,7-carbazole monomer unit was synthesized and used to prepare two poly(2,7-carbazole)s, both of which were obtained in relatively high molecular weight and display excellent solubility in common organic solvents. The polymers were able to effectively disperse carbon nanotube bundles in both THF and toluene using a relatively simple procedure to yield concentrated polymer-carbon nanotube samples that were stable for months. The polymer-coated carbon nanotube samples were characterized by thermogravimetric analysis, atomic force microscopy, absorption spectroscopy, photoluminescence mapping, and Raman spectroscopy. It was found that the polymers used in this study preferentially interact with carbon nanotubes having diameters of 1.15 nm or less. Additionally, it was observed that the carbon nanotubes remained effectively debundled by the polymers after removal of solvent, as was demonstrated by Raman and photoluminescence mapping of solid films of the polymer-carbon nanotube composites.
