Synthesis of Pyrene-Anthracene Conjugated Molecular Rods
نویسندگان
چکیده
Fully conjugated pyrene-anthracene-based molecular rods were synthesized by the Horner-Wadsworth– Emmons reaction utilizing potassium tert-butoxide in dry THF. The synthesized rods, which have butylene groups as solubility spacers in the main chain, exhibited good solubility in polar solvents. The solutions of the synthesized pyrenecontaining molecular rods exhibited a blue shift in the UV-vis from the absorption maximum due to the presence of the pyrene group in comparison with the dialdehydes. The chemical structure and purity of the synthesized rods were confirmed by H and C NMR, FAB+, MALDI-TOF, electrospray mass spectra and elemental analysis.

DNA-like fluorescent oligomers composed of alkynyl beta-D-ribofuranosides bearing pyrene, perylene, and anthracene as a fluorophore were synthesized by solid-phase DNA synthesis. The fluorescent oligomers possess the defined number and order of the fluorophores. In these oligomers, the adjacent fluorophores efficiently interact with each other by hydrophobic interactions in their electronic gro...
متن کاملOxidation of Anthracene and Benzo[a]pyrene by Laccases from Trametes versicolor.
The in vitro oxidation of the two polycyclic aromatic hydrocarbons anthracene and benzo[a]pyrene, which have ionization potentials of <=7.45 eV, is catalyzed by laccases from Trametes versicolor. Crude laccase preparations were able to oxidize both anthracene and the potent carcinogen benzo[a]pyrene. Oxidation of benzo[a]pyrene was enhanced by the addition of the cooxidant 2,2(prm1)-azinobis(3-...
