Synthesis of disk-shape liquid crystalline materials using multi-component reactions is reported. Two new series, the compounds I (R = n-CnH2n+1; n = 6, 7, 8, 10, 11, 12) and II, were synthesized by coupling either 2,3-dihydroxynaphthalene or 2,6-dihydroxynaphthalene with the corresponding 3,4,5-tris(alkoxy)anilines under solvent-free conditions. The mol. structures of the new materials were confirmed using 1H NMR, 13C NMR and CHN elemental anal. The phase behavior was investigated using polarizing optical microscope and differential scanning calorimetry experiments All the materials exhibited room temperature discotic nematic phase during the cooling cycles as confirmed by X-ray diffraction studies. This synthetic approach provides multiple advantages such as high atom economy, short reaction time, mild reaction condition, simple workup, and do not require column chromatog. purification

This manuscript describes a synthetic strategy and structure-property investigation of unprecedented phosphonium-based zwitterionic homopolymers (polyzwitterions) and random copolymers (zwitterionomers). Free radical polymerization of 4-(diphenylphosphino)styrene (DPPS) provided neutral polymers containing reactive triarylphosphines. Quant. postpolymn. alkylation of these pendant functionalities generated a library of polymers containing various concentrations of neutral phosphines, phosphonium ions, and phosphonium sulfobetaine zwitterions. The zwitterionic homo- and copolymers exhibited significantly higher glass transition temperatures (Tg) and enhanced mech. reinforcement in comparison to neutral and phosphonium analogs. These changes in Tg and mech. properties were attributed to nanoscale morphol. domains, which formed due to electrostatic interactions between zwitterionic groups, as revealed by X-ray scattering and broadband dielec. spectroscopy (BDS). BDS revealed increased static dielec. constants (>25) for the phosphonium zwitterionomers compared to ionomeric or neutral analogs. These high static dielec. constants for the solvent-free polyzwitterions supported their stronger polarization response in comparison with polymers containing neutral phosphines and phosphonium ions, and these interactions accounted for morphol. differences and enhanced mech. behavior. This work describes a versatile strategy for modulating electrostatic interactions with tunable mech. properties for an unprecedented family of zwitterionic polymers.

New coumarin esters, (E)-4-[[[7-(octyloxy)-2-oxo-2H-chromen-3-yl]imino]methyl]phenyl-4-alkyloxybenzoates, containing a Schiff base linkage in which an octyloxy chain is at one end and different long terminal alkoxy chains (C2-C18) are at the other end, have been synthesized and studied for their mesomorphic behavior. The investigation of phase and mesophase transitions was carried out using differential scanning calorimetry and a Polarized Optical Microscope. The mesomorphic investigation revealed that all new derivatives exhibited an enantiotropic nematic phase and, except for two compounds, I [R = CnH2n+1, n = 2, 3], all the members also displayed enantiotropic smectic C phase in addition to enantiotropic nematic phase. The new mesogens mesomorphic behavior of all synthesized compounds were thoroughly studied and discussed, as well as compared with structurally comparable substances. Finally, the DFT theor. calculations were studied and compared with the exptl. to explain the relationship between the structural parameters and the mesomorphic behavior.

An original and efficient copper-catalyzed 1,6-hydrodifluoroacetylation of para-quinone methides with difluoroalkyl bromides has been described with bis(pinacolato)diboron (B2pin2) as reductant. In this reaction, a new C(sp3)-CF2 bond is constructed under smart conditions. A broad substrate scope of para-quinone methides (p-QMs) make this protocol very practical and attractive. Preliminary mechanistic studies manifested that a difluoroalkyl radical pathway was involved in this reaction. Also the presence of the diboron reagent was an essential requisite in this transformation.

It was reported that the side chains play especially an important role in enhancing phys. properties and energy levels. Polythiophene based on benzodithiophene has excellent carrier mobility, but high HOMO level. We synthesized polythiophenes, PBDTBiTh(2EH) and PBDTBiTh(12C), were polymerized using the Stille coupling reaction and had thiophene with a 2-ethylhexyl or n-dodecyl side chain. Upon introducing the 2-ethylhexyl side chain, the absorption coefficients of the monomers and polymers were enhanced. Also, the edge-on orientation was fortified and the HOMO level was decreased to -5.37 eV. PBDTBiTh(2EH) showed a power conversion efficiency (PCE) of 2.1%, which was double that of PBDTBiTh(12C).

Quaternary N-alkyl tropinium cationic surfactants (TILS) were synthesized and characterized. The effect of temperature, hydrophobic chain length and anions on their properties were studied. By changing the structure of anion, the krafft point was significantly reduced (from 313.15 K to <273.15 K) and wide temperature window was obtained. The critical micelle concentration (CMC) value of TILS based on elec. conductivity method is decreased ∼4-5 times by increasing hydrophobicity of anions. At lower temperature and longer hydrophobic chain, TILS had lower CMC value and better surface activity. The thermodn. properties of micellization Gibbs free energy ΔGmic, enthalpy ΔHmic and entropy TΔSmic of micelles were obtained by Mass action model. The micellization process of the TILS was spontaneous and more stable with the increase of anionic hydrophobicity. With the increase of hydrophobic side chain length, the driving force of surfactant micellization may be enthalpy driven at higher temperature and entropy driven at lower temperature The micro-environment of TILS solution with different concentrations was studied by UV spectrophotometry with curcumin as a probe and the change of micro-environment was used to determine the CMC of TILS. The CMC values were similar obtained by 2 methods.

Monomers with large surface area and high quantum yield, that was fluorescent flippers, were engineered into twisted push-pull oligomers to create membrane probes with high mechanosensitivity and long fluorescence lifetime. The synthesis and characterization of thieno[3,4]pyrazines and 2,1,3-benzothiadiazoles were described in comparison with the original dithienothiophene S,S-dioxides. Dithienothiophene S,S-dioxide flippers were confirmed as the best reported so far, and poor results with single flipper probes support that two flippers were needed for the probe to really ‘swim’ i.e., for high mechanosensitivity.
