Synthesis and optical reactivity of 6,13-α-diketoprecursors of 2,3,9,10-tetraalkylpentacenes in solution, films and crystals

Tetraalkylpentacenes having alkyl chains at 2,3,9,10-positions (Et-PEN, Pr-PEN and Hex-PEN) were prepared from their precursors Et-PDK, Pr-PDK and Hex-PDK, respectively. Photoreactions proceeded both in solutions, thin-films, and crystals, thus the properties of Et-PDK in films can be studied despite the instability of the pentacenes in solution. Et-PEN showed significantly different aggregation-nature compared with the parent pentacene. The hole mobilities of Et-PEN and Pr-PEN in films were 3.4 × 10-6 and 8.1 × 10-7 cm2 V-1 s-1, respectively, determined by space-charge-limited current measurement, comparable with the order 10-6 cm2 V-1 s-1 of the electron mobility of Alq3.

Synthesis of Alkyl- and Alkoxy-Substituted Benzils and Oxidative Coupling to Tetraalkoxyphenanthrene-9,10-diones

Intermolecular Friedel-Crafts acylation of various substituted alkyl- or alkoxybenzenes with oxalyl chloride using carbon disulfide as solvent gave rise to the benzils 1a-k.Subsequent intramolecular oxidative coupling with either thallium(III) oxide/trifluoroacetic acid or vanadium(V) oxyfluoride/boron trifluoride diethyl etherate resulted in the corresponding phenanthrene-9,10-diones 2a-d.It has been shown that oxygen functionalities at the 3,3',4, and 4'positions are necessary for coupling to occur.These substituted benzils and phenanthrene-9,10-diones constitute precursors for ligands in the field of discotic metallomesogens or polymeric mesogens.

Synthesis of Diacetylene Macrocycles Derived from 1,2-Diethynylbenzene Derivatives: Structure and Reactivity of the Strained Cyclic Dimer

Diacetylene macrocycles 2-4 (n=1-3) (R=H, C4H9, C6H13, C10H21, C12H25, OC10H21) have been prepared from the oxidative coupling of 1,2-diethynylbenzene derivatives.These compounds can be produced in useful quantities and are of interest as precursors to novel conjugated organic polymers.The reported results indicate that when the R groups are large the dimeric macrocycle (n=1) can be prepared in as high as 74percent yield from the corresponding 1,2-diethynylbenzene in a one-step procedure.An alternate multistep procedure was found to produce the tetrameric macrocycle (n=3,R=C6H13) in 45percent yield.The highly strained dimeric macrocycle was characterized by an X-ray structure and was found to be very reactive.The dimers undergo a rapid very exothermic polymerization at 100-125 deg C, indicative of a chain reaction.Reaction of the dimeric macrocycles with iodine results in intramolecular cyclization and a new 20? electron tetraiodide fused ring system.Reaction of the tetraiodide with oxygen produces a related compound in which two of the iodides have been converted to ketones.

Discotic Liquid Crystals of Transition Metal Complexes 11: The First ?-Acceptor in Discotic Columnar Liquid Crystals Obtained from Octasubstituted Bis(diphenylethane-1,2-dithiolene)nickel Complexes

Disk-like complexes, bisnickel (n-alkyl = n-hexyl, n-octyl) and bisnickel have been synthesized and characterized.It was found that n-decyloxy derivative exhibits a hexagonal discordered columnar (Dhd) mesophase while n-alkyl derivatives are not discotic liquid crystals but isotropic liquids at room temperature.The half-wave potentials for reduction of these complexes is -0.04 - -0.06 V. n-Decyloxy derivative is the first ?-acceptor in discotic columnar liquid crystals.

NATURE OF THE OIL/WATER INTERFACE AND EQUILIBRIUM SURFACTANT AGGREGATES IN SYSTEMS EXHIBITING LOW TENSIONS

Oil/water interfacial tensions are reported for systems containing pure alkane, aqueous sodium chloride, and a pure anionic surfactant, either Aerosol OT or p-dihexylbenzene sodium sulphonate (DHBS).Evidence is produced to support the claim that monolayer adsorption at the oil/water inteface can produce ultralow tensions (ca. 1 μN m-1), and that the presence at the interface of a third, surfactant-rich phase is not necessary.The aggregation of DHBS and its distribution between oil and aqueous phases of various salinities have been investigated.It has been confirmed that the behaviour of DHBS in these respects is similar to that of Aerosol OT, as might be expected from its molecular structure.The sizes of microemulsion droplets in equilibrium with planar adsorbed monolayers have been determined, and related to the tensions of the plane oil/aqueous phase interfaces using simple existing theory.
