Octakis(2-benzyloxyethylsulfanyl) Copper (II) Phthalocyanine: A New Liquid Crystalline Discotic Material with Benzyl-Terminated, Thioether-Linked Side Chains

摘要: The synthesis and materials properties of a new liquid crystalline phthalocyanine, octakis (2-benzyloxyethylsulfanyl) copper (II) 2, are reported. This phthalocyanine possesses eight benzyl-terminated side chains with thioether links to the Pc core, which promote greater interaction between discotic mesogens than has been seen in previous Pcs reported from this group had alkoxy-based chains. use these promotes red-shift Q-band absorbance spectrum, small decreases first oxidation potential, increased solution aggregation constants, significantly higher K→LC transition temperatures conventional side-chain-modified Pcs. Powders single crystals material were characterized by X-ray diffraction found represent two closely related polymorphs. Room-temperature XRD powders 2 showed monoclinic unit cell:  = 22.81(1) A, b 9.780(5) c 19.314(6) α 90°,...
