Self-assembly of a fluorescent galunamide derivative and sensing of acid vapor and mechanical force stimuli

A galunamide derivative consisting of a fluorophore with benzoxazole and a cyano unit was designed and synthesized to realize a dual response to acid vapor and mechanical force. Photophysical properties and self-assembly were investigated. The dilute solution could respond to the acid stimulus, and the emission peak at 472 nm shifted to 535 nm with the addition of trifluoroacetic acid (TFA). Moreover, the derivative could self-assemble into thin nanofibers in its gel phase, and the fluorescence of the xerogel film is sensitive to TFA vapor. The emission color gradually changed from yellow to orange red upon exposure to acid vapor, and the detection limit is as low as 70 ppb for TFA. The solid exhibited a reversible fluorescence color change under the stimuli of mechanical force and solvent annealing. The UV-vis absorption and IR spectra indicate that the fluorescence color conversion can be attributed to the destruction of intermolecular hydrogen bonds and pristine π-π interaction induced by mechanical force.

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.

Columnar liquid-crystalline phase from a series of symmetrical bent diphenylamine derivatives: Synthesis and characterization

A series of symmetrical bent-shaped materials with six alkoxy chains at the terminal position has been designed and synthesized. All except one exhibit columnar mesophase behavior. The mesomorphic properties of the compounds have been studied with the help of polaralizing optical microscopy (POM) and differential scanning colorimetry (DSC) experiments.

Self-assembly of imidazolium-based rodlike ionic liquid crystals: transition from lamellar to micellar organization

By using aryl-amination chemistry, a series of rodlike 1-phenyl1H- imidazole-based liquid crystals (LCs) and related imidazolium-based ionic liquid crystals (ILCs) has been prepared. The number and length of the C-terminal chains (at the noncharged end of the rodlike core) and the length of the N-terminal chain (on the imidazolium unit in the ILCs) were modified and the influence of these structural parameters on the mode of self-assembly in LC phases was investigated by polarizing microscopy, differential scanning calorimetry, and X-ray diffraction. For the single-chain imidazole derivatives nematic phases (N) and bilayer SmA2 phases were found, but upon increasing the number of alkyl chains the LC phases were lost. For the related imidazolium salts LC phases were preserved upon increasing the number and length of the C-terminal chains and in this series it leads to the phase sequence SmA-columnar (Col)-micellar cubic (Cuby1/Pm3n). Elongation of the N-terminal chain gives the reversed sequence. Short Nterminal chains prefer an end-to-end packing of the mesogens in which these chains are separated from the C-terminal chains. Elongation of the N-terminal chain leads to a mixing of N- and C-terminal chains, which is accompanied by complete intercalation of the aromatic cores. In the smectic phases this gives rise to a transition from bilayer (SmA2) to monolayer smectic (SmA) phases. For the columnar and cubic phases the segregated end-to-end packing leads to core-shell aggregates. In this case, elongation of the N-terminal chains distorts core-shell formation and removes Cub1 and Col phases in favor of single-layer SmA phases. Hence, by tailoring the length of the N-terminal chain, a crossover from taper-shaped to polycatenar LC tectons was achieved, which provides a powerful tool for control of self-assembly in ILCs.
