Synthesis and Characterization of Near-Infrared Emissive Chiral π-Conjugated Polymers Incorporating Perylenyl Moieties with Visible-Light Absorption

A novel set of multifunctional optically active π-conjugated polymers incorporating perylenyl moieties, were designed and synthesized. Chirality transfer and amplification from chiral unit to the main-chain backbone in dilute solution was achieved, which was closely related to the stereocenter in the pendant of a π-conjugated polymer. In addition, annealed films of these polymers exhibited near-infrared emission by direct absorption of visible light, resulting from the introduction of a strong fluorophore perylenyl moiety. Such a design strategy opens up new perspectives for the future development of novel optically active materials with near-infrared emission for photonic applications.

Light-driven supramolecular chirality in propeller-like hydrogen-bonded complexes that show columnar mesomorphism

(Graph Presented) Shine a light! Columnar mesomorphic assembles of propeller-like hydrogen-bonded complexes show a chiral photo-response upon irradiation with circularly polarized light (CPL) of a given handedness (see picture). The materials can behave as a supramolecular switch that undergoes helix inversion when irradiated with the oppositely polarized light.

A study of the thermodynamical interactions with solvents and surface characterisation of liquid crystalline 5-((S)-3,7-dimethyloctyloxy)-2-[[[4-(dodecyloxy)phenyl]imino]-methyl]phenol by inverse gas chromatography

An inverse gas chromatography (IGC) study of thermodynamic interactions of a new chiral calamitic liquid crystalline 5-((S)-3,7-Dimethyloctyloxy)-2-[[[4-(dodecyloxy)phenyl]imino]methyl]phenol (DODPIMP) with some solvents was presented. The retention diagrams of the solvents on the DODPIMP were plotted by specific retention volumes, Vg0 at temperatures between 373.2 and 393.2?K. The Flory-Huggins interaction parameter, χ12∞, the weight fraction activity coefficient, Ω1∞ and selectivity coefficients, α, of the structural isomers were determined for the DODPIMP liquid crystal. To characterize the surface properties of, retention diagrams of several non-polar and polar solvents on the DODPIMP were plotted by net retention volumes, VN in the temperature range from 303.2 to 318.2?K. The dispersive surface energy, the thermodynamic adsorption parameters and the acid–base constants of the compound in the crystalline phase were determined. The results indicated a basic character for the surface of DODPIMP at the studied conditions.

Large Faraday Rotation in Optical-Quality Phthalocyanine and Porphyrin Thin Films

The magneto-optical phenomenon known as Faraday rotation involves the rotation of plane-polarized light as it passes through an optical medium in the presence of an external magnetic field oriented parallel to the direction of light propagation. Faraday rotators find applications in optical isolators and magnetic-field imaging technologies. In recent years, organic thin films comprised of polymeric and small-molecule chromophores have demonstrated Verdet constants, which measure the magnitude of rotation at a given magnetic field strength and material thickness, that exceed those found in conventional inorganic crystals. We report herein the thin-film magnetic circular birefringence (MCB) spectra and maximum Verdet constants of several commercially available and newly synthesized phthalocyanine and porphyrin derivatives. Five of these species achieved maximum Verdet constant magnitudes greater than 105 deg T-1 m-1 at wavelengths between 530 and 800 nm. Notably, a newly reported zinc(II) phthalocyanine derivative (ZnPc-OT) reached a Verdet constant of -33 × 104 deg T-1 m-1 at 800 nm, which is among the largest reported for an organic material, especially for an optical-quality thin film. The MCB spectra are consistent with resonance-enhanced Faraday rotation in the region of the Q-band electronic transition common to porphyrin and phthalocyanine derivatives, and the Faraday A-term describes the electronic origin of the magneto-optical activity. Overall, we demonstrate that phthalocyanines and porphyrins are a class of rationally designed magneto-optical materials suitable for applications demanding large Verdet constants and high optical quality.

The synthesis and dielectric properties of a new phenylbenzoate-based calamitic liquid crystal

The dielectric investigation has a great importance in liquid crystal studies as a supportive method to DSC for a complete characterization of liquid crystals as well as in the electronic applications. In this study, the synthesis, mesomorphic characterization and dielectric properties of a new phenylbenzoate-based three-ring calamitic liquid crystal which composed of ester linking groups, (S)-3,7-dimethyloctyloxy chiral unit at one of terminals and n-octyloxy chain at the other end of the molecule, have been reported. The new calamitic liquid crystal 4-[4-((S)-3,7-dimethyloctyloxy)phenoxy)carbonyl]phenyl 4-(n-octyloxy)benzoate (DPCPB) has been characterized using 1H, 13C-NMR and MS-QTOF. The liquid crystalline behavior of the target compound has been investigated by differential scanning calorimetry and optical polarizing microscopy. DPCPB exhibits an enantiotropic non-tilted smectic mesophase in a wide temperature range. The real and imaginary dielectric constant, conductivity mechanism, impedance and dielectric relaxation mechanism of DPCPB have been investigated depending on frequency at different temperatures.
