Novel phenazine fused triphenylene discotic liquid crystals: synthesis, characterisation, thermal, optical and nonlinear optical properties

A straightforward synthesis of novel phenazine fused triphenylene discotic liquid crystals (DLCs) is realized. The condensation of 3,4-diaminobenzoic acid with a triphenylene-1,2-diquinone intermediate gives an acid derivative which upon esterification with aliphatic alcohols produces the corresponding monomeric ester derivatives of the phenazine fused triphenylene discotic liquid crystals. The intermediate acid derivative exhibits a rectangular columnar phase along with a high isotropic phase transition temperature. However, the monomeric ester derivatives show a hexagonal columnar mesophase over a broad temperature range and stable when decreased to room temperature upon cooling from the isotropic phase. The mesomorphic properties of the acid and monomeric ester derivatives of the phenazine fused triphenylene DLCs were characterised by polarised optical microscopy (POM), differential scanning calorimetry (DSC) and X-ray diffraction studies (XRD). The molecular structures of the intermediate and final compounds were characterised by spectral and elemental analysis. The photophysical properties of all the monomeric ester compounds were investigated in an anhydrous chloroform solvent and absorption bands around 291-472 nm and the corresponding emission bands at 658-661 nm were observed, respectively. The π-extended conjugation in these materials gives rise to high nonlinear optical properties. These materials have immense potential for use in electro-optical applications.

2,1,3-Benzothiadiazole-based fluorophores. Synthesis, electrochemical, thermal and photophysical characterization

Three photoactive compounds with π-extended conjugation based on the 2,1,3-benzothiadiazole unit were synthesized and characterized. The compounds exhibited absorption in the violet-blue region with molar absorptivity coefficients and radiative rate constants arising from spin and symmetry allowed 1ππ* electronic transitions. An emission located in the green region with a large Stokes shift was observed, which was most likely due to a charge-transfer mechanism in the excited state. In spin-coated films a dependence on the fluorescence emission intensity with the size of the alkoxy chain could be observed, where an effective non-radiactive channel seems to be present to deactivate the excited state. The thermal properties were analyzed by differential scanning calorimetry (DSC), and all final compounds exhibited a similar behavior with a crystal-isotropic liquid transition during the heating scan and isotropic liquid-crystal transition during the cooling process. Thermogravimetric analysis indicated a main thermal event with an initial decomposition temperature that was higher than 340?°C. The electrochemical characterization indicate that the compounds exhibited a reversible peak at ?1.48?V and an irreversible oxidation process at 0.94?V versus Ag/Ag+. The electrochemical band gap was calculated to be approximately 2.30?eV versus NHE. The spectroelectrochemical measurements demonstrated changes in the absorption spectra due to changes in the electronic structure of the conjugated molecules under oxidative and reductive potentials.

Synthesis and self-assembly of phthalocyanine-tethered block copolymers

A series of novel phthalocyanine (Pc)-tethered block copolymers, Pc-poly(methyl methacrylate)-block-polystyrene (Pc-PMMA-b-PS), with various molecular weights (number average molecular weight mass = 41, 66, 86 kg mol-1), were prepared by atom transfer radical polymerization and click chemistry. The structurally related Pc-tethered homopolymer, Pc-PMMA was also synthesized for comparison. Pc-PMMA forms homogeneous polymer films containing π-assemblies of the terminal Pc groups, whereas Pc-PMMA-b-PS self-assembles into a cylindrical morphology in which the Pc units show π-π interactions inside the confined PMMA cylinders. Such polymer designs have potential applications in optoelectronic devices. This journal is

Correlation of structure and photovoltaic performance of benzo[1,2-b:4,5-b′]dithiophene copolymers alternating with different acceptors

Four π-conjugated benzo[1,2-b:4,5-b′]dithiophene (BDT) based polymers were synthesized for application in polymer solar cells. These polymers possessed desirable HOMO/LUMO levels for polymer photovoltaic applications. PBDTT-TTz and PBDTT-DTBT displayed strong absorption in the range of 300-650 nm, while PBDTT-DPP and PBDTT-TTDPP showed a further 100 nm extended absorption band. The lowest unoccupied molecular orbital energy levels of polymers were tuned effectively from -3.34 eV to -3.81 eV by fusing with different accepting units. A maximum power conversion efficiency of 2.60% was obtained from photovoltaic cells with a PBDTT-TTz:PC61BM (1:2, w/w) blend film as the active layer, with a short circuit current density of 8.37 mA cm-2, an open circuit voltage of 0.70 V, and a fill factor of 44.3%.
