Functionalizable polycyclic aromatics through oxidative cyclization of pendant thiophenes

We present a general strategy for obtaining large sulfur-containing polycyclic aromatics from thienyl precursors through iron(Ill) chloride mediated oxidative cyclizations. By placing thienyl moieties in close proximity to adjacent arenes, we have directed the oxidized intermediates into controlled cyclization pathways, effectively suppressing polymer formation. Utilizing these cyclized compounds and their thienyl precursors, we have studied cyclization/polymerization pathways of polymers such as poly(2). The unsubstituted positions α to the sulfur atoms within these aromatic cores allowed for efficient halogenation and further functionalization. As a demonstration, we prepared a series of arylene-ethynylene polymers with varying degrees of chromophore aromatization and used them to probe the effects of synthetically imposed rigidity on polymer photophysical behavior. The symmetries and effective conjugation pathways within the monomers play a key role in determining photophysical properties. We observed that rigid, aromatized chromophores generally led to increased excited-state lifetimes by decreasing radiative rates of fluorescence decay.

Turn-on detection of pesticides: Via reversible fluorescence enhancement of conjugated polymer nanoparticles and thin films

Reported herein is the significant fluorescence enhancement of conjugated polymer nanoparticles in the presence of aromatic organochlorine pesticides. This pesticide-mediated fluorescence enhancement leads to reversible pesticide detection systems with hi

Columnar catenar bisoxazoles and bisthiazoles

Three new series of catenar liquid crystals 1a-c derived from heterocyclic bisoxazoles and bisthiazoles exhibiting columnar phases were reported. All compounds 1a-c exhibited hexagonal columnar phases, which were confirmed by powder XRD diffractometer. Co

A straightforward route to electron transporting conjugated polymers

We report a straightforward synthetic method to generate solution processable electron transporting polymers with low band gap and wide absorption range from readily available acceptor monomers. We show the efficacy of this approach using widely used elec

Two-dimensional porous molecular networks of dehydrobenzo[12]annulene derivatives via alkyl chain interdigitation

The self-assembly of a series of hexadehydrotribenzo[12]annulene (DBA) derivatives has been scrutinized by scanning tunneling microscopy (STM) at the liquid-solid interface. First, the influence of core symmetry on the network structure was investigated b

Synthesis and specific features of mesomorphic behavior of new polysubstituted triphenylenes

Previously unknown 2,3,6,7,10,11-hexakis(dodecyloxy)triphenylene and -(tetradecyloxy)triphenylene were synthesized. The structures of the synthesized compounds were proved by elemental analysis and spectral methods. Polymesomorphism was found for the first time and studied for substances of the hexaalkoxytriphenylene homologic series, as well as liotropic mesomorphism in a series of organic solvents.

Ionic columnar metallomesogens formed by three-coordinated copper(I) complexes

Two series of copper(I) complexes (1,2) derived from bis{2-[3′-(3″,4″-dialkoxyphenyl)-5′-methyl-1′- pyrazolyl]ethyl} ethers and from bis{2-[3′-(3″,4″,5′-trialkoxyphenyl)-5′- methyl-1′-pyrazolyl]ethyl} ethers were prepared and characterized. These ionic copper(I) complexes were obtained by reaction of the ethers with [Cu(MeCN)4]BF4 in refluxing acetonitrile. All three-coordinated copper(I) complexes isolated as off-white solids were characterized by NMR spectroscopy and elemental analysis, and their mesomorphic properties were also studied by polarized optical microscopy, differential scanning calorimetry (DSC) and powder X-ray diffraction (XRD). Results indicated that these complexes exhibited hexagonal columnar phases (Colh). The clearing points of all compounds were relatively low (94-112°C) and the temperature range of the mesophases was ca. 45-68°C. Powder XRD diffraction patterns showed three sharp reflections in the small angle region corresponding to a ratio of their positions of 1:(1/3)1/2:(1/2), indicating typical hexagonal columnar phases.

Analogues of Platelet Activating Factor. 6. Mono- and Bis-Aryl Phosphate Antagonists of Platelet Activating Factor

A series of aryl phosphoglyceride (3, 19-61) and bis-aryl phosphate (67-135) antagonists of platelet activating factor (PAF) were prepared.A group of four bifunctional phosphorus reagents (5a-c and 7) were developed that allowed the preparation of these aryl phosphates in which the position of aromatic substitution can be varied.These compounds were examined for their ability to inhibit PAF-induced platelet aggregation of rabbit platelets.Selected compounds were also evaluated for their ability to displace PAF from its receptor on rabbit platelets.These in vitro data were compared to similar data obtained for a number of known PAF antagonists.The compounds were evaluated in vivo, in both the mouse and rabbit, for their ability to prevent death induced by a lethal challenge of PAF.The relationships between the biological activity and the nature, lipophilicity, and position of substituents of the aromatic rings were studied.Compound 105 (CL 184005) has been selected to undergo further development as a potential therapeutic agent for the treatment of septic shock in man.
